"Simple, elemental, yet full of heart, the story, remarkably, captures a character who isn’t there and makes readers see him just as Leon does." – BOOKLIST
Leon is new in town and doesn’t know anyone. That’s when he makes friends with Bob. No one else can see Bob, but Leon knows he’s there. One day a boy exactly Leon’s age moves in next door. Leon would like to meet him, as long as Bob comes along. But suddenly Bob is gone. How alone Leon feels! Is he brave enough to make friends without Bob beside him?
