With nationwide calls for police reform and defunding, literary giant John Grisham’s novel A Time for Mercy is undoubtedly timely, as it explores the ways that violence committed by or against law enforcement officials can complicate the pursuit of justice.

Jake Brigance—the hero of Grisham’s 1989 debut, A Time to Kill—is court-appointed to represent 16-year-old Drew Gamble in the shooting death of his mother’s boyfriend, deputy sheriff Stu Kofer. There’s no question that Drew pulled the trigger, but Jake faces an ethical challenge over whether the shooting was justified. Drew contends that he shot Stu in self-defense after believing Stu had killed his mother. Drew, his younger sister and their mother lived in constant fear of beatings by Stu, who often returned home in a drunken stupor.

Jake only wants to handle preliminary matters for the Gamble case until a permanent public defender can be appointed. But deep down, he realizes he’s the best chance the Gamble family has. With public sentiment and fellow police officers standing behind Stu and his family, Jake’s efforts to keep Drew from being tried as an adult and facing possible execution put him at odds with the community.

While there are lulls during some of the legal procedural bits, Grisham’s mastery of the courtroom thriller is never in question. As usual, he presents as smooth a read as you’ll ever experience. The dialogue is sharp and pointed, layered with genuine emotions that make the characters pop off the pages of this morally complex story.

Brilliant hacker-turned-MI6-agent Brigitte Sharp (she goes by “Bridge”) feels torn between opposing forces. She’s a member of the British intelligence agency’s elite cyber threat analytics unit and an excellent field agent, but she’s reluctant to leave desk duty since a failed mission three years ago. She’s close to her sister and friends but has become weary of lying to them to protect her cover. And her drive to seek justice has been tamped down by PTSD-fueled fear that she’ll harm someone because of her perceived incompetence.

Now, as Antony Johnston’s The Exphoria Code opens, Bridge’s life has come to a crisis point: Her boss and therapist are insisting she get back to fieldwork just as she learns her online friend Tenebrae_Z has been found dead—perhaps as a result of their attempts to decrypt mysterious ASCII (an electronic character encoding standard) art that the two came across online.

Bridge “had always thought of the truth as a mountain peak. . . . To reach it, you might have to negotiate tricky paths, shifting scree, falling boulders. But if you were persistent enough . . . you could eventually reach the summit and the truth would be revealed.” She comes up against a veritable mountain range of obstacles as she investigates Ten’s murder. For starters, the ASCII posts are related to a top-secret Anglo-French project involving military drones—a project that’s got a mole in its ranks, as well as plenty of dangerous people invested in keeping Bridge from finding out who the mole is or what nefariousness he or she is up to.

Johnston, perhaps best known for his graphic novel The Coldest City (which served as the source for the film Atomic Blonde), has once again created a heroine who’s as smart and savvy as she is badass. He lays a complex trail of clues, hazards and betrayals as Bridge goes undercover to track down the mole and ends up in tense interrogations, edge-of-your-seat chases and action-packed fights to the possible death. Can she unearth the mole before something terrible happens? Readers will thrill to the chase in this kickoff to a techno-thriller series that has at its center a hacker with a heart of gold—and nerves of steel.

Virgil Wounded Horse is a man living tentatively between two worlds. On the one hand, he feels an obligation to his Lakota upbringing. On the other, the tragic deaths of his mother and sister have caused him to drift away from this heritage. But when his 14-year-old nephew, Nathan, nearly dies after a heroin overdose, Virgil’s loyalties are put to the test. A recovering alcoholic, Virgil vows to protect his family and his tribe as best he can by seeking out those bringing the drugs into his community and exacting his revenge.

The police are no help on South Dakota’s Rosebud Indian Reservation, so it falls to men like Virgil to mete out the tribe’s own brand of justice when necessary. When the trail leads off reservation, however, and into the purview of the FBI, Virgil’s hands are tied. The only way around it may be by allowing the Feds to use Nathan as a confidential informant in a pair of drug buys, or else Virgil may see his nephew imprisoned in an adult institution for distribution of narcotics.

Virgil’s quest for justice is further complicated when he is reunited with his former girlfriend, Marie, who still embraces much of their heritage. The daughter of Ben Short Bear, who is running for tribal president, she is torn by the opportunity to attend medical school off campus, which could mean leaving the reservation and Virgil behind.

On the surface, David Heska Wanbli Weiden’s debut novel, Winter Counts, is somewhat typical for its genre: Bad guys disrupt the status quo when they muscle into the community, pushing bad drugs on an unsuspecting and highly susceptible teen population, until a vigilante or detective pushes back. The difference here is the setting on the Lakota reservation, the clash of policies between the U.S. government and Native American life, and the internal conflicts of the novel’s main characters.

Weiden, who is a member of the Sicangu Lakota Nation, elevates an otherwise routine crime novel with Native American culture and traditions, political differences and organized crime. His well-rendered, emotionally charged characters do the rest.
