Former academic Arthur Opp weighs 550 pounds and hasn't left his rambling Brooklyn home in a decade. Twenty milesaway, in Yonkers, seventeen-year-old Kel Keller navigates life as the poor kid in a rich school and pins his hopes on what seems like a promising sporting career-if he can untangle himself from his family drama. The link between this unlikely pair is Kel's mother, Charlene, a former student of Arthur's. After nearly two decades of silence, it is Charlene's unexpected phone call to Arthur-a plea for help-that jostles them into action. Through Arthur and Kel's own quirky and lovable voices, Heft tells the winning story of two improbable heroes whose sudden connection transforms both their lives.
