A Chicago Tribune Best Children's Book of the Year 2018 Booklist Youth Editors' Choice New York City Public Library Notable 100 Best Books for Kids "A welcome addition to the middle-grade canon and will likely become a classic." — San Francisco Book Review It's been five years since Livy and her family have visited Livy's grandmother in Australia. Now that she's back, Livy has the feeling she's forgotten something really, really important about Gran's house. It turns out she's right. Bob, a short, greenish creature dressed in a chicken suit, didn't forget Livy, or her promise. He's been waiting five years for her to come back, hiding in a closet like she told him to. He can't remember who—or what—he is, where he came from, or if he even has a family. But five years ago Livy promised she would help him find his way back home. Now it's time to keep that promise. Clue by clue, Livy and Bob will unravel the mystery of where Bob comes from, and discover the kind of magic that lasts forever . . . "A perfectly paced plot, supported by secondary characters to whom readers will relate and luminous artwork by Gannon, fill out a story that readers will eagerly embrace. VERDICT: A must-have for libraries serving middle grade readers, this novel delights." — School Library Journal (starred review)
