Deborah Hopkinson

This deceptively simple picture book explores the emotions we feel when friendships end. Deborah Underwood’s story focuses on Walter, a rodent-ish fellow with white fur, round ears and a long pink tail. Walter’s best friend is Xavier, a yellow duck-like creature whose feet and flat beak are green.

The two friends do everything together. They hike, paint pictures, float in a rowboat and just enjoy sitting quietly. Their friendship changes, however, when a hedgehog named Penelope appears, and she and Xavier begin spending more time with each other. 

Gradually, Walter’s world is transformed. He experiences anger, loneliness and sadness as Xavier gravitates more and more toward Penelope. Especially evocative is a scene in which Penelope and Xavier have invited Walter to a ball game. It rains, and the new friends share an umbrella while Walter sits apart from them, miserable and wet. 

Underwood’s spare text provides ample space for illustrator Sergio Ruzzier’s surreal, otherworldly landscapes and bright pastel color palette. Ruzzier depicts the impact of Walter’s loss in approachable, moving images. For instance, we learn that Walter is quiet, “but it was a sad quiet. Not best friend quiet.” The accompanying spread shows Walter sitting alone on a dock; a dangling rope nearby suggests that the rowboat has been launched without him. He has lost not only his friend but also the pleasures they enjoyed together.

Just as Walter loses his friendship with Xavier slowly, his recovery is also slow, But he misses the activities he used to do with Xavier, so one bright day, when rays of sunshine beam through the closed curtains at his house, he just can’t resist the urge to go on a hike. Instead of taking the old trail, he strikes out on a new one—and discovers the promise of a new friendship along the way.

The book’s gentle pace, engaging artwork and lyrical yet straightforward text make this a comforting, reassuring read for young readers experiencing transitions at school or with friends. Walter Had a Best Friend is a gem.

When Walter’s best friend finds a new best friend, Walter’s world is transformed in this comforting, reassuring picture book.

Author Marina Budhos has previously explored the experiences of immigrants, particularly Muslim teens after 9/11, in two acclaimed YA novels, Ask Me No Questions and Watched. We Are All We Have is set in 2019, after the U.S. Department of Justice implemented a zero-tolerance policy toward illegal immigration. The novel follows 17-year-old Rania, whose late father was a political journalist in Pakistan. Rania lives in Brooklyn, New York, with her mother and younger brother, Kamal, who was born in the U.S. As the novel opens, Rania is looking forward to spending the summer with friends before attending Hunter College on a scholarship she received for “literary promise.”

But Rania’s world is shattered in a single night when her mother is arrested by Immigration and Customs Enforcement and sent to a detention facility in Pennsylvania. Rania and Kamal’s legal situation becomes even more complicated when the neighbor who agreed to serve as their guardian changes her mind, afraid of being deported herself. Before Rania can track down an estranged uncle who may be able to help, a neighbor reports her and Kamal for living without a guardian and they are taken to an understaffed shelter in Manhattan.

At the shelter, Rania meets Carlos, a young artist from Mexico. Carlos hatches a plan that will allow him, Rania and Kamal to escape the shelter and attend Rania’s graduation—and then keep on running. During her summer on the road, Rania uncovers secrets about her mother and the circumstances of her own birth. On Cape Cod, Carlos and Rania take on temporary jobs until they realize the only way to redeem their futures is to face the present.

We Are All We Have is compelling and vivid, filled with drama, family secrets and romance. Budhos conducted extensive research for the novel, which included visiting courtrooms and meeting with experts on immigration law. Her conversations revealed that “though we consider ourselves an immigrant nation, our bedrock ideal rests on a capricious and ever-changing set of laws and policies.” Budhos’ fully realized characters and urgent prose bring these laws into sharp focus for teen readers.

In this compelling, vivid novel, Rania’s world is shattered in a single night when her mother is arrested and detained by U.S. immigration officials.

New York Times bestselling author Alexandra Horowitz (Our Dogs, Ourselves) has done it again. She’s created a heartwarming and personal story about dogs that seamlessly incorporates captivating science about our beloved canine companions. In The Year of the Puppy: How Dogs Become Themselves, Horowitz, a specialist in canine cognition and head of the Dog Cognition Lab at Barnard University, follows the first year of a puppy’s life—her own family’s new puppy, as it happens.

In part one, Horowitz describes the birth and early development of their puppy, Quiddity (Quid). Many owners never experience the early weeks—or even years, with many rescues—of their dogs’ lives, and this section makes fascinating reading as Horowitz meets not just her puppy but the puppy’s mom: Maize, a young dog surrendered to a shelter in Georgia when her owners realized she was pregnant. Maize was transported to New York, where she was fostered by an experienced woman named Amy who took on responsibility for the new mom and her pups—11 in all, it turns out.

In part two, Horowitz and her family choose Quid as their own, and she traces the puppy’s weekly development and integration into their family, where every experience is new: new people, new big dogs, new cat, new house. Training at the outset consists of taking Quid out to pee every two hours and rewarding her for positive behaviors—though the puppy often moves through 12 behaviors in 10 seconds. Fortunately, there are also naps.

Horowitz writes with a gentle humor that any pet owner will appreciate. “After bringing a puppy home, that potential dog vanishes and is replaced by an actual biting, running, peeing, whining dog in our home every hour of every day,” she writes. “She bites the cat in the face and bothers the dogs, who have taken, rightfully, to just turning away in disdain.”

The book is more than an entertaining personal narrative, however. Along the way, Horowitz draws on her extensive knowledge to offer insights into canine behavior. She goes beyond training-focused instructional manuals to show that often what humans label as “misbehavior” is actually normal puppy behavior. We expect dogs to live in our world. But, as Horowitz chronicles one year in Quid’s life, she gently urges us to become more aware of the incredibly rich and complex world dogs inhabit. The better we understand our pooches, the more likely we are to succeed at providing a wonderful home for everyone.

It’s a given that for dog lovers, The Year of the Puppy is a must-read. But even cat lovers will find much to enjoy in this endearing scientific memoir.

Alexandra Horowitz has created another heartwarming and personal story that seamlessly incorporates captivating science about our canine companions.

Two of America’s most distinguished figures in children’s literature combine their formidable talents to create a moving biography of the great Maya Angelou. In Maya’s Song, Newbery Honor author Renée Watson (Piecing Me Together) chronicles the pivotal milestones and emotional touchstones of Angelou’s extraordinary life in a series of lyrical free verse poems, lavishly illustrated with four-time Caldecott Honor recipient Bryan Collier’s vibrant watercolor and collage artwork. The result, like Angelou herself, is an American treasure.

In addition to plays, essays and poetry, Angelou penned seven autobiographical works, and it would be a challenge for any biographer to encompass all the details of her complex, eventful life. Watson handles this challenge easily in a 48-page picture book format.

Watson’s beautiful, heartfelt poems provide young readers with both historical and emotional context, while a concluding timeline provides factual highlights. In 1993, Angelou became the first woman and first Black person to present an original poem at a presidential inauguration. She achieved another first in 2022, when her likeness became the first portrait of a Black woman to be featured on the U.S. quarter.

Watson’s exquisite poems are enhanced by Collier’s evocative art. In his illustrator’s note, Collier (All Because You Matter) invites readers to examine the way he uses color, especially blue, to illuminate Angelou’s tumultuous childhood, which included a devastating sexual assault by her mother’s boyfriend. The trauma she experienced and the man’s subsequent murder left Angelou mute for five years. It’s impossible to tell Angelou’s life story without this event. Watson does so with sensitivity, telling readers that “When Maya was seven years old, / her mother’s boyfriend / hurt her body, hurt her soul,” placing the focus on Angelou’s recovery through literature, poetry and the love of her family, especially her grandmother and brother.

Angelou was many things: a poet, a dancer, a singer, a world traveler, an award-winning author and a civil rights activist who counted figures such as James Baldwin and Martin Luther King Jr. as friends. Most of all, she was an inspiration. In her author’s note, Watson describes being moved to tears the first time she heard Angelou speak. “I have held Maya Angelou’s words close to me my whole life,” she writes. “Her words guide me, heal me, inspire me.” Young readers who meet Angelou through Maya’s Song will surely look at her face on the U.S. quarter with a better understanding of the remarkable woman who earned such a tribute.

Through lyrical poems and lavish watercolor and collage artwork, Renée Watson and Bryan Collier create a moving biography of the remarkable Maya Angelou.

Yes, you read the title correctly. This is indeed an autobiography of our galaxy, and yes, it is nonfiction. The Milky Way’s debut book—a creative, humorous and enormously entertaining one at that—comes to us earthlings via Dr. Moiya McTier, who studied both mythology and astronomy at Harvard before earning her Ph.D. in astrophysics at Columbia University. 

The galaxy begins its life story this way: “Take a look around you, human. What do you see? Actually, don’t answer that. Why would I bother listening to you when I know you’ll get it wrong?” The Milky Way, it seems, is rather a stuck-up know-it-all. (Superior, omniscient, haughty—perhaps a bit like your cat. As Dr. McTier explains in the acknowledgements, whenever she needed to get into the Milky Way’s voice, she would look at her cat, Kosmo.) Although, once you stop to think about things from our galaxy’s perspective, it’s easy to see why. After all, the Milky Way is more than 13 billion Earth years old and home to more than 100 billion stars. Impressive, to say the least.

Read the Milky Way’s behind-the-scenes story of how an ancient galaxy managed to land a book deal.

And that’s just the beginning. In chapters covering its early years, growing pains, constellations and modern myths, the Milky Way details a page-turning life story, full of drama (massive black holes!), major changes (the death of stars!) and tumultuous relationships with neighboring galaxies, such as Andromeda. It is quite adept at explaining complex scientific concepts to us (vastly more ignorant) humans, but the most surprising aspect of this book is that the Milky Way has a buoyant sense of humor, as well as a passion for “inspiring others.”

As with any translation from another tongue, readers may marvel at the role of the translator in creating a book that is both informative and truly inspirational. Here, it’s clear Dr. McTier has harnessed the sense of marvel she felt as a child, when she imagined the sun and moon as celestial parents who watched over her and talked to her on a regular basis. That childlike wonder, combined with her expertise in mythology and astronomy, makes her the perfect human to assist in telling this story.

At any rate, since the Milky Way took the time to help us all understand more about our universe, it would be only polite to put this highly recommended title at the top of your reading list.

As told to Dr. Moiya McTier, the Milky Way details its page-turning life story, full of drama and humor.

We may think we know what intelligence is. After all, human intelligence is what enables us to read intriguing nonfiction books such as If Nietzsche Were a Narwhal: What Animal Intelligence Reveals About Human Stupidity by animal behavior and cognition researcher Justin Gregg, who works with the Dolphin Communication Project at St. Francis Xavier University in Nova Scotia. But as Gregg makes clear in his engaging third book, we might not know as much as we think about intelligence. In fact, we might be entirely wrong in our assumptions. It might be time to seriously question “human exceptionalism” and what it means for our species and our planet. To do that, Gregg sets out to answer the question “What good is human intelligence?”

Justin Gregg, author of ‘If Nietzsche Were a Narwhal,’ extols the virtues of stupid animals.

The author begins with a chapter about humans as “why specialists.” Anyone who has been in the presence of a toddler will recognize the “Why?” stage of development. While we may automatically assume that this ability to ask—and discover answers to—every question under the sun is uniformly positive, Gregg asks us to look at this human characteristic through a different lens: “I propose we consider a provocative premise: does asking why give us a biological advantage?” Gregg then takes readers on a time-travel expedition, from 240,000 years ago until today, to demonstrate why certain qualities associated with human intelligence have not, evolutionarily speaking, benefited either our species or the Earth. When humanity’s answers to “why questions” are wrong, Gregg explains, they lead to some truly terrible outcomes, including white supremacy and genocide.

Gregg takes readers on a wide-ranging, entertaining journey of discovery in If Nietzsche Were a Narwhal, challenging them to reexamine their assumptions about animals and humans. Along the way, he explores aspects of human experience (such as language use, morality, awareness of death and our capacity to wonder about virtually everything in the universe) and reveals ways in which nonhuman animals experience consciousness themselves. All together, If Nietzsche Were a Narwhal is a timely, thought-provoking and often sobering book that will make you look at humans, animals and the future of our planet with new eyes.

According to cognitive scientist Justin Gregg, we might be entirely wrong in our assumption that human intelligence is a good thing.

Young astronomer Mable loves to listen to Grana’s stories, but her grandmother is ill and “too weak to tell stories now.” As Mable stays close to Grana’s bedside, she looks up at the sky through a telescope, making maps of the constellations. “If we can touch the moon,” Grana asks her granddaughter, “then what is impossible?”

Later that night, Mable embarks on a quest to “make impossible things possible” by touching the moon. After a countdown, she rockets into the sky like a spaceship. As she soars among the constellations, she recognizes fantastical figures from her grandmother’s tales of African mythology and African American history, including an archer, a pair of twins and a friendly dog. When Mable stops for a sip of water from the drinking gourd, she sees tracks that remind her of the Underground Railroad. Eventually, she begins to feel tired, and a group of celestial women cocoon her in a blanket of stars until she falls asleep. No miracle awaits when Mable awakens the next morning, but Grana feels well enough to sit up and ask Mable to tell her a story.

Author Breanna J. McDaniel’s prose is warm and inviting. Grana’s illness seems severe, but McDaniel constructs a comforting, hopeful narrative that emphasizes the strong, loving relationship between Mable and her grandmother. In the book’s backmatter, McDaniel (Hands Up!) movingly describes Impossible Moon‘s personal origins. She also provides brief descriptions of the constellations Mable encounters and explains their roles in African American culture.

Illustrator Tonya Engel’s oil and acrylic illustrations are richly hued and playful. Small flames trail behind Mable’s feet as she shoots up into the sky, a rocket ship of a girl. Brilliant blues evoke the dreamlike atmosphere of Mable’s nighttime adventure, while tiny splatters of white and yellow convey the vast number of distant stars.

Readers who enjoyed Antwan Eady and Gracey Zhang’s Nigel and the Moon won’t want to miss this fresh, imaginative lunar tale. It belongs on the nightstands of young dreamers everywhere.

Mable embarks on an imaginative journey to touch the moon in this lunar tale perfect for readers who loved Antwan Eady and Gracey Zhang’s Nigel and the Moon.

Readers may be most familiar with Ed Yong from his Pulitzer Prize-winning science writing for The Atlantic. His first book, the New York Times bestselling I Contain Multitudes, explored the world of microbes. In his new work of nonfiction, An Immense World, Yong tackles the realm of animal senses, taking readers on a fascinating journey backed up by impressive research.

Yong’s scope is far-reaching, and the issues and scientific concepts involved are sometimes complex. But much like a skilled mountain guide, he takes the time to prepare readers for what lies ahead. In the introduction, Yong not only identifies basic terms (such as stimuli, sense organs and sensory systems) but also provides guideposts for the journey ahead, challenging readers to use their imaginations in order to overcome the blind spots humans inevitably have when trying to understand sensory systems immensely different from our own. As Yong writes, “Our intuitions will be our biggest liabilities, and our imaginations will be our greatest assets.”

Subsequent chapters do indeed engage the imagination. Yong’s book is organized by different senses, some which are familiar—such as smell, taste and sound—and others much less familiar. In a chapter titled “The Rippling Ground: Surface Vibrations,” we learn about scientist Karen Warkentin’s groundbreaking discovery that embryonic tadpoles can hatch early if they sense a snake attack. Other such fascinating anecdotes abound throughout this book, and it’s safe to say readers will have a hard time not sharing newfound knowledge in daily conversation. For example, did you know that Philippine tarsiers emit sounds with frequencies above the ultrasonic boundary, or that 250 species of fish can produce their own electricity?

Yong brings to this project a supreme mastery of science writing for the general reader, so don’t be intimidated by the nearly 50-page bibliography. An Immense World is an accessible, illuminating and endlessly exciting reading experience. Yes, nonfiction about science can be page-turning!

While this title is perfect for adult nature lovers, the accessibility of Yong’s approach also makes this a wonderful gift for high school or college students interested in science. For at its heart, this treasure of a book is a sober reminder of what’s at stake in the 21st century—and today’s students will be tomorrow’s researchers and citizen scientists. “A better understanding of the senses can show us how we’re defiling the natural world,” Yong writes in his closing chapter. “It can also point to ways of saving it.”

An Immense World is an accessible, illuminating and exciting reading experience. Yes, nonfiction about the science of animal senses can be page-turning!

The life of a 19th-century poet, painter and gardener is vividly captured in Celia Planted a Garden: The Story of Celia Thaxter and Her Island Garden, a lovingly written and illustrated nonfiction picture book. It’s a fruitful collaboration by award-winning writers Phyllis Root and Gary D. Schmidt, with colorful, engaging illustrations by Melissa Sweet.

As a young child, Celia Thaxter (née Laighton) moved with her family from Portsmouth, New Hampshire, to White Island, part of the Isle of Shoals archipelago off the coasts of New Hampshire and Maine, where her father became the island’s lighthouse keeper. In 1847, when Thaxter was 12, her father built a large hotel on nearby Appledore Island. Thaxter worked in the hotel and planted a garden on its grounds.

The hotel attracted summer visitors, including well-known artists and writers such as Henry Wadsworth Longfellow and Nathaniel Hawthorne. Thaxter blossomed as her relationships with these creative figures opened up her world. Eventually, they encouraged Thaxter to write stories and poems about her life on the island and helped her find publication.

Thaxter moved to Watertown, Massachusetts, after she married, but she continued to spend summers on Appledore Island. During the winter months, she wrote and painted greeting cards and china pitchers, bowls and plates. Today, Thaxter is best known for her 1894 book, An Island Garden, illustrated by the American impressionist painter Childe Hassam, and for her garden on Appledore, which was re-created and restored in 1977.

Root and Schmidt’s accessible text focuses on Thaxter’s lifelong love of nature. Sweet incorporates hand-lettered quotations from Thaxter’s own writing, bringing her poetic voice into many of the book’s gorgeous spreads: “The very act of planting a seed has in it to me something beautiful.” Although Celia Planted a Garden contains substantial back matter, including a biographical note, a timeline of Thaxter’s life and an annotated bibliography, specific citations for Thaxter’s quotations aren’t include, which is a notable omission considering their prominence in the book.

Much like Barbara Cooney’s beloved Miss Rumphius, Celia Planted a Garden evokes the magic of summers in Maine and the joy of tending flowers. And like that classic picture book, Celia Planted a Garden is sure to inspire a new generation of young gardeners everywhere.

This picture book biography of 19th-century poet, painter and gardener Celia Thaxter evokes the magic of summers in Maine and the joy of tending flowers.

Puzzles are big news—and big business—these days. With their capacity to entertain, challenge and provide a distraction from the stresses of daily life, puzzles have found a wider audience than ever before.

In the introduction to his new book, The Puzzler: One Man’s Quest to Solve the Most Baffling Puzzles Ever, From Crosswords to Jigsaws to the Meaning of Life, journalist, bestselling author and invenerate puzzler A.J. Jacobs (The Know-It-All) shares the euphoria he felt upon learning that his name was featured as a clue in a New York Times crossword puzzle. He’d made it to the big time! But, alas, it was a Saturday puzzle, one of the hardest of the week. So, not a household name just yet, just an obscure clue.

However, Jacobs may find his name appearing in clues more often as puzzle lovers old and new discover this timely and entertaining exploration of why we love (and, yes, often become addicted to) all sorts of puzzles—from the word puzzle books we gobbled up in childhood, to jigsaw puzzles on card tables during family summer vacations, to the world’s recent embrace of a simple daily word game. (You know the one.)

A.J. Jacobs shares how he solved the hardest puzzle yet: motivating himself to finish writing ‘The Puzzler.’

Jacobs covers a wide variety of puzzles, including anagrams, mazes, math and logic puzzles, Rubik’s Cubes, Sudoku, riddles, ciphers and, of course, crosswords—his first love. He admits to knowing the exact time the New York Times crossword puzzle appears online each day. He’s also honest about the emotions involved in puzzle-solving. Frankly, it’s not all enjoyment; there’s frustration, drama, despair and even humiliation. “And sometimes there’s terror,” Jacobs writes, speaking of the creeping fear that getting stuck portends mental decline.

The Puzzler isn’t simply Jacobs’ personal journey, however; it’s also an exploration of the history of puzzles and their role in society. Along the way, Jacobs meets and interviews some fascinating puzzle lovers, including Jeff Varasano, who created his own algorithms to solve a Rubik’s Cube as a teenager back in 1980, and a young woman named Sydney Weaver, a “speedcuber” whose cubing has helped her with pediatric arthritis. Readers also meet crossword maker Peter Gordon, who, when asked why he thinks we’re addicted to puzzles, replied, “Well, life is a puzzle.” Indeed, as the late Maki Kaji, often known as the father of Sudoku, believed, puzzles are a journey. Jacobs’ wonderful book reminds us that puzzles help us to be present in the moment and connect with others on the same journey.

A final note: The Puzzler would make a fabulous gift as a physical copy simply because it includes original puzzles by Greg Pliska for readers to solve. But don’t despair; the answers are in the back.

Puzzle lovers old and new will be thrilled to discover this entertaining exploration of why we love (and often become addicted to) all sorts of puzzles.

Magda Hellinger was a 25-year-old Jewish kindergarten teacher when she was deported to Auschwitz from Slovakia in March of 1942. She was one of the few who survived more than three years in a concentration camp, eventually relocating to Australia, where she lived to be almost 90. During her lifetime, Hellinger shared her experiences in interviews with organizations such as the United States Holocaust Memorial Museum, all while secretly writing a memoir of her experiences at Auschwitz-Birkenau.

The Nazis Knew My Name is grounded in that memoir, self-published in 2003, but enhanced by Hellinger’s daughter, Maya Lee, who has added further research and details from her mother’s oral testimonies. The result is a compelling and seamless portrait of a young woman who managed to survive and save others through cunning bravery and compassionate leadership.

At the core of Hellinger’s approach was this: “I constantly encouraged women to work together—a very simple form of resistance. A lonely, isolated woman was always more vulnerable than one who had others looking out for her.” Her determination and use of resistance tactics emerge time and again in this chronological account of her imprisonment, which lasted until the end of World War II.

When Hellinger was given the role of block leader at Auschwitz, she realized it was crucial that the prisoners under her charge avoid any behavior that would attract attention from Nazi officials. She therefore focused on trying to keep the women under her care as healthy as possible, making sure newcomers understood the rules of the camp and warning them of the most volatile guards. And while it was dangerous to challenge SS officers directly, at key moments Hellinger did exactly that, often risking her own life to win some small concession, such as replacing worn clothing for the prisoners.

The strain of Hellinger’s various roles must have taken an enormous psychological toll. At one point, she had 30,000 women under her care, yet she didn’t falter and always returned to the touchstone of cooperation. She mobilized others to improve sanitary conditions, ensure that food was distributed fairly and hide the most vulnerable prisoners to prevent them from being selected for the gas chamber. “If we could do these things, we might save a few lives, or make life a little more bearable,” Hellinger writes. “But we had to work together.”

The Nazis Knew My Name offers dreadful insights into the workings of Auschwitz-Birkenau, but at its heart, it remains an extraordinary portrait of one young woman who fought for others in the midst of unimaginable horror.

Holocaust survivor Magda Hellinger offers a compelling memoir of fighting for others in the midst of unimaginable horror.

In his debut picture book, Nigel and the Moon, author Antwan Eady introduces a young boy named Nigel Strong. Every night, Nigel travels to the moon to share his hopes and aspirations. Nigel wants to go to space as an astronaut or leap like a ballet dancer, but most of all, he’d love to become a superhero.

During career week at school, Nigel is beset by doubts. As he pages through books about occupations at the library, he doesn’t find any dancers with brown skin who look like him. While his classmates eagerly announce what they want to be when they grow up, Nigel holds back. It’s one thing to share his secret dream of being a superhero with the moon, but quite another to say it out loud in his classroom. And when his classmates discuss their parents’ occupations, Nigel asks to be excused, worried that everyone will laugh because his parents don’t have “fancy jobs.”

But when Nigel’s mom, a postal carrier, and his dad, a truck driver, visit his class on the final day of career week, their enthusiasm for their work lights up the room. Nigel, too, beams with pride after his dad declares, “Raising Nigel’s been the best job we’ve ever had.” His parents’ support gives Nigel the courage he needs to share his dreams with his peers.

Illustrator Gracey Zhang’s ink, gouache and watercolor illustrations vividly capture the lush green trees and brightly colored houses over which Nigel soars each night on his way to the moon. Zhang’s images expertly convey Nigel’s emotions. The deep blue of the night sky and the large, luminous moon complement his nightly musings. In one spread, while his classmates share what their parents do for a living, Nigel sits at his desk on the opposite page, isolated and alone, surrounded by white space.

Eady’s spare text tells a simple but powerful story about believing in yourself and being proud of your family. A final, wordless image shows Nigel peering out his bedroom window at the moon once more, inviting readers to wonder what he might be dreaming of—and to consider their own hopes and dreams, too.

Nigel and the Moon tells a simple but imaginative story about believing in your dreams and finding the courage to share them with others.
Interview by

Greg Brennecka is a cosmochemist with a sense of humor and a flair for making complex topics both understandable and entertaining. We asked him to share a little scientific advice for all those who feel inspired to study the stars after reading Impact.


No doubt you get this a lot, but what exactly is a cosmochemist?
Ha, well, most people don’t even ask—probably because they just figure it’s something completely made up. I guess I would properly define cosmochemistry as the study of extraterrestrial materials with the goal of understanding the origin and evolution of our solar system and our cosmic neighborhood. But basically, it’s just looking at stuff not from Earth to learn cool things.

The subtitle of your book is quite memorable: How Rocks From Space Led to Life, Culture, and Donkey Kong. What was your history with Donkey Kong before writing Impact?
To be honest, I am more of a Ms. Pac-Man fan, but I also enjoyed the original Donkey Kong arcade game quite a bit growing up. I also usually choose a Donkey Kong character when racing in Mario Kart because I love throwing bananas all around the course. Please don’t hate me for that.

Your book brims with wit and humor. Have you ever considered stand-up cosmochemist comedy?
If there is a job more made up than “cosmochemist,” it is “stand-up cosmochemist comedian”!

Read our starred review of ‘Impact’ by Greg Brennecka

Many of the concepts in Impact are highly technical and complex, yet you’ve found a way to make them accessible to readers. What’s your secret?
My secret is that I am not that great at discussing things in a technical way! I think it helps that a lot of the questions we ask in geology and meteoritics are straightforward questions, such as “When did this happen?” or “What happened that could make it look like this?” There may be some technical aspects to how we get at the answers, but the questions and goals themselves are usually very relatable to readers of all backgrounds, and I think that makes my job as a writer a lot easier.

Asteroids have been in the news of late, with NASA’s Double Asteroid Redirection Test (DART) mission. What excites you most about it?
One thing to keep in mind with DART: It’s conceivable that we will need to adjust the path of an asteroid to keep it from hitting Earth someday, so making sure we know how to do that is a pretty sound preparation. And I know that “sound preparation” isn’t usually associated with excitement, but I am always very excited by humanity striving to do cool and difficult things, advancing our capabilities.

What’s the most common question about asteroids that you get?
For asteroids specifically, probably whether Earth is going to be hit by one—which probably isn’t a surprise given the popular Hollywood movies on the subject. When it comes to meteorites—the small chunks of asteroids that land on Earth—I sometimes get asked about being hit by one, but also often about what they are worth if you find one. I guess that tells us pretty clearly what motivates people: fear and money.

“Basically, it’s just looking at stuff not from Earth to learn cool things.”

If you could be magically transported to another planet so you could get a better look, which would you choose?
Oooh, that is tough. I would probably be most interested in a planet’s potential ability to harbor life, so it would be hard to argue with Mars. Do moons count? Because if so, probably one of the moons of Jupiter or Saturn, like Europa or Enceladus. There are some potentially habitable exoplanets that are being discovered almost daily now, as well, so some of those would be incredible to check out up close.

If you could go back in time on Earth, what would you want to see most?
Wow. I would probably want to figure out how life got its start on Earth, so I would travel to sometime around 4 billion years ago. If I had a second choice, perhaps Cretaceous age or so when the dinosaurs were cruising around. I wouldn’t last long, but it would be an exciting few minutes!

What has been your most breathtaking experience looking through a telescope?
For me, it probably didn’t even take place while using a telescope. Just lying down and looking at the stars in places without light pollution, I get a real feeling for how vast, diverse and dynamic the cosmos are. It blows me away every time I get the chance.

“I am always very excited by humanity striving to do cool and difficult things.”

Your book combines a love of history with a love of science. Who are some of the writers who have influenced you?
This is an easy one: Bill Bryson. His A Short History of Nearly Everything was an incredibly influential book for me and really got me into learning about the history of science and culture. I reread it in 2017, and the lack of information about meteorites is what inspired me to write Impact. I also really enjoy stuff by Mark Kurlansky (Salt) and Yuval Noah Harari (Sapiens: A Brief History of Humankind).

Your book ends with a discussion of some of the most fascinating unanswered questions in space science. What research are you working on now?
My colleagues and I are working on a few different topics mentioned in the book. One is searching for the source of water on Earth. Currently we are doing this using lunar rocks, of all things, but I think we are onto something, so keep an eye on the scientific literature. Secondly, we are working on what I like to call “cosmolocation,” which is studying meteorites to find out where they originally formed in the solar system. Basically, this involves re-creating the solar system’s structure from when it first started—before all the planets formed and moved everything around to where it is now.

There’s a long tradition of amateur astronomers. What advice do you have for someone who wants to start studying the night sky?
This might be a weird answer, but I would let them know that they don’t need to buy that big backyard telescope as a first step. There is so much open-access data available from NASA and other agencies that people can just poke through and make discoveries on their own using data about the surface of Mars or deep space images from space telescopes like Hubble. There is a lot yet to be discovered in those data troves, should one feel like getting involved.

A bona fide meteor master shares the secret behind his accessible, fascinating and funny debut, Impact.
