Ethan Pritcher is a normal kid. Well, other than the fact that every once in a while, he switches bodies with someone else. He doesn't know how or why, he just knows that it happens—and always when he least expects it. After trading identities with a muscle-bound movie star, Ethan finds himself in a big trouble. When he learns that a hired killer is after him, just staying alive will be a big challenge. But his sister, Madison, may have the toughest job of all. She'll have to find a way to keep the movie star, now inhabiting Ethan's body, from getting her brother kicked out of sixth grade. . .
