The Bloody Sun (First Revised Edition) (Darkover)

Darkover! For some the planet beneath the bloody far-off sun had the reputation of being a half-frozen lump of dust on the edge of nowhere. For Terran Jeff Kerwin, this distant planet he remembered only as a childhood dream was home. Years of planning brought him back to Darkover, but he found no peace there. From the first day he set foot on the planet he had been hounded by a sinister, swarthy man who made no secret of his shadowing. Then there was the strange discovery that no record of his birth and childhood existed. And there was the jewel he always wore around his neck; a Darkovan matrix crystal, with powers he had no awareness of. First revision of the original Ace paperback; thus, the second overall edition.
