The Bloody Sun

For Jeff Kerwin, Darkover meant home, the home he had left as a child, the home he had longed for through the many years. Yet, he was to be terribly disappointed when he finally returned. First he learned that there were not records of any kind of either his birth or childhood on Darkover. And then, after he renounced his Terran allegiance and joined the natives attempting to free Darkover from Earth's control, the Darkovans accused him of being a spy.

Someone was betraying them. Had Jeff been conditioned on Earth for just that purpose? Jeff Kerwin began to wonder just who, and what, he really was.
