The Bloody Sun
Author: Marion Zimmer Bradley
 
Darkover had once been home to Jeff Kerwin - a home he'd left and then yearned after for many years. But when, finally, he returned it was to mystery and fear.
For there was no record of his birth there, nor of his childhood. And when he joined the freedom fighters whoo struggled to overthrow Earth's control of the planet, the Darkovans accused him of being a spy.
Had Jeff been conditioned, on Earth, to betray Darkover? He, himself, was no longer sure of who - or what - he really was!
