Laurel Snyder is the author of many books for children, including the Theodor Seuss Geisel Award–winning Charlie & Mouse. She lives and writes in a small yellow house in Atlanta, Georgia, which she shares with her husband and two sons.

Chuck Groenink hails from a village in the north of the Netherlands, where he spent his formative years climbing trees, drawing, reading, and cycling. He lives in Syracuse, New York.

★“In this clever tribute to Maurice Sendak, Snyder and Groenink gleefully subvert picture book norms by embracing the beastliest behavior”
—Publishers Weekly, starred review

“Rightly and properly dedicated to Maurice Sendak . . . A reassuring promise that it's OK to be beastly.”
—Kirkus Reviews

“Use this at story hour and expect giggles, shrieks, and groans.”
—Booklist

“A definite celebration of his style and not an outright copy, this is a must-have for fans of Sendak who adore tales of wildness; sure to have readers young and old giggling with joy.”
—School Library Journal
