Interstellar travel to alien worlds is too expensive for Marvin, a college student in need of a good vacation. And so he signs up for what he can afford: a mind swap, in which his consciousness is swapped into the body of an alien life-form. Unfortunately, Marvin finds himself in the body of an interstellar criminal—a body that he has to vacate, fast. But that criminal consciousness has stolen Marvin's earthly body. Now Marvin has to find a body on the black market just to stay alive! Travel with Marvin from world to world, each one crazier than the last, as he keeps finding far-from-ideal bodies in awful situations.
