리비네 가족이 할머니가 사는 호주에 방문한 지도 5년이 지났다. 리비는 할머니댁과 관련한 아주 아주 중요한 무언가를 잊어버린 것 같은 느낌이 들었다. 그리고 그 느낌이 맞았다.

치킨 수트를 입은 키가 작고 초록빛의 밥이 리비와 리비의 약속을 잊지 않고 있었다. 리비가 돌아오길 5년 동안이나 기다리며 리비가 시킨대로 옷장에 숨어서 기다렸던 것이다. 밥은 스스로가 누군지도, 어디에서 왔는지도, 가족이 있는지도 전혀 기억하지 못했다. 하지만 5년 전 리비는 밥이 집에 돌아갈 수 있도록 도와주겠다고 약속했었다. 이제 그 약속을 지킬 때가 왔다.

Wendy Mass and Rebecca Stead, two masterminds of classic, middle-grade fiction come together to craft this magical story about the enduring power of friendship.

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.
