Master storyteller Gordon Korman balances humour and heart in this reinvention story about a bully who must come to terms with who he was and what kind of person he wants to become. Chase Ambrose forgets everything after falling off a roof and losing consciousness. He forgets his name. He forgets his parents. He forgets what he was doing up there on that roof. And he forgets that he's the biggest bully at Hiawassee Middle School, along with his two best buddies Aaron and Bear. Chase is shocked to learn how he bullied and tormented kids at school. He ruined lives. One kid left town because of him. And worst of all, even his little half-sister is terrified of him. Was he really such a monster? Determined to reinvent himself, Chase joins video club and befriends some of the kids who used to consider him a number-one enemy. But some people aren't so quick to forgive and forget. Can Chase really change who he is? Or will the old him merely come back over time?
