Everyone in Sam Keeperman's fifth-grade class thinks the new boy, Buddy White, is strange. Buddy won't talk, or smile, or even pick up a pencil, and he walks all hunched over, like someone caught in the rain. Some of the kids make fun of Buddy, but not Sam. That's because Sam knows what's bothering him: Three months ago, Buddy's mom was killed in a car accident. She used to clean Sam's house, and ever since Sam found out what happened to her, he can't get her out of his mind. Sam sticks up for Buddy, but the other kids start picking on Sam, too. Even Sam's best friend turns against him. The more time Sam spends with Buddy—and the more Buddy comes out of his shell—the more Sam understands what it means to lose someone you love. And what it means to be a friend.
