Brandon is the biggest and toughest kid in his small-town school. He is feared as a bully, but he only pretends to be "dumb as a bag of hammers," so he can learn as much as possible about the people around him. When Leon, his sister Winnie, and their lively little brother Sam, arrive in Kingsville, they are the only black people in town. Everyone is curious about them—where they came from, what their parents do—but when Brandon discovers the truth about their situation, he decides to do what he can to protect them from harm.
