Interstellar travel to alien worlds is certainly very costly for Marvin, a scholar looking for a good vacation. Therefore he signs up for what he are able: a mind swap, where his consciousness is normally swapped in to the body of the alien life-form. However, Marvin discovers himself in the body of the interstellar criminal-a body that he must vacate, fast. But that legal consciousness has taken Marvin’s earthly body. Right now Marvin must look for a body around the dark market merely to stay alive! Travel with Marvin from globe to world, each one crazier compared to the last, as he will keep finding far-from-ideal body in awful situations.
