Nick Crandall feels like he doesn't belong anywhere. He never has felt like he belongs, really. He doesn't fit in this new family with his new foster parents, both of whom are professors. They don't know the first thing about sports—and he's not exactly a model student. It's only a matter of time until they realize he's not the right kid for them. And Nick certainly doesn't belong playing varsity baseball. He's only twelve years old! His teammates want a catcher their own age, not some kid. But Nick needs to prove something. He needs to prove that he belongs—to his parents, to his team, and to himself.
