Yellow Elephant: A Bright Bestiary celebrates animals and colors with poems by Julie Larios and the vibrant artwork of Julie Paschkis. Although recommended for ages 5 to 10, the book would be especially appropriate for younger children just learning their colors and animals. Some of the animals imitate nature: a white owl, a green frog and a gray goose ( Gray mama goose in a tizzy, honk-honk-honking herself dizzy ) while others leap off the page in bright, vivid colors: Yellow elephant in the jungle sun . . . trumpeting her song and galumphing along.Deborah Hopkinson's new book, a Junior Library Guild selection entitled Up Before Daybreak: Cotton and People in America, will be published this month.
