Ten-year-old Elijiah Breeze, a.k.a. Jumper, is having the hardest summer of his life. His father has just died; his mother has moved them from the suburbs to New York City's Harlem area; and he has to spend the summer at baseball camp. Basketball is Jumper's game. He doesn't know anything about baseball, or city life, or how to keep going without his dad. He finds out it is possible to start over in a new place with new people...and still hold on to what's important from his past.
