"It's been five years since Livy and her family have visited Livy's grandmother in Australia. Now that Livy's back, she 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. Wendy Mass and Rebecca Stead, two masterminds of classic middle-grade fiction, come together to craft an enduring tale about the magic of friendship and the power of childhood." -- Back cover
