On Jupiter's moon Ganymede, an alien life-form has taken over the body of a human astronaut, creating an almost perfect copy. But perfect enough to escape discovery on the long return trip to Earth? Can the deadly counterfeit be detected and stopped before its hunger for new life can endanger an entire planet?
