Chase's memory just went out the window. Chase doesn't remember falling off the roof. He doesn't remember hitting his head. He doesn't, in fact, remember anything. He wakes up in a hospital room and suddenly has to learn his whole life all over again…starting with his own name. He knows he's Chase. But who is Chase? Pretty soon, it's not only a question of who Chase is, it's a question of who he was…and who he's going to be.
Review from School Library Journal Starred:
What would it be like to forget your whole life, your family, your friends, and even who you are? After falling off his roof, 13-year-old Chase Ambrose learns the hard way that reinventing himself can be pretty hard, especially when his past is not what he wants for his future. Before his fall, Chase was a jock, captain of the football team, following in his father's footsteps. He was also the biggest bully in his middle school, had made many students' lives miserable, and was serving a community service sentence for the damage that his bullying had caused. Even Chase's little stepsister was afraid of him. If it were up to his dad and his former best friends, Bear and Aaron, Chase would go right back to his bully-jock ways. However, the new Chase is a kinder, more sympathetic person who struggles with his past and becomes friends with his former victims. As he works with the video club geeks, he forms a relationship with elderly Mr. Solway. Korman juxtaposes Mr. Solway's sharing of his Korean War memories with Chase's search for his own past. Despite the strong antibullying theme, the story is never preachy or trite but thoughtfully presents questions about loyalty, identity, and the possibility of a new start in a way that appropriately fits the middle school setting.
