Outcast in space. Michael Trehearne had always been an outcast among his people on Earth. He knew he was different. He did not know how or why. Then one day, on the wind-swept coast of Brittany, a bewitchingly beautiful girl appeared and told him he had the look of the Vardda—those elite star travelers who alone could withstand the rigors of intergalactic flight.

Michael had to join them, had to find his place in the universe at last. But it would not be easy. For even when they allowed him to risk his life aboard their ship, to seal his fate upon their planet, even then, they viewed him as an outcast, a dangerous changeling who suddenly threatened them. He was a man who sooner or later would have to be destroyed!
