The Man With a Thousand Names: Mittend was the closest inhabitable planet to Earth, even though 30 light-years distant. A bored young heir, Steven Masters, contrived to join the first manned expedition just for a bit of excitement. When he found himself suddenly back on Earth in another man's body, it was more than he'd expected. Next was a kaleidoscope of events that was to involve him in muliple personalities, in more expeditions to Mittend, and in the affairs of the entity for whom Mittend was just a means to an end - and Steven Masters the handy next step in a galactic program.
