The sole survivor on a science vessel adrift in deep space, Zeus was adopted by the Emperor and Empress of the Mar'Sani, though he is both human and blind, and seen by most as unfit to join the royal family. Though they were able to repair his vision, Zeus does not trust his eyes and the nobles of his parents' court refuse to ever trust a frail human. Dargon Kal-Turak, along with his symbiote and lover Alpha, command one of the most dangerous ships in the stars. Narrowly escaping a trap, they dock in a space port to make repairs, but find that the Psonics hunting them are closing in fast. In desperation they kidnap the port Master Mechanic, unaware that the man they've brought on board is more than he seems, and will bring far more upheaval to their ship, their lives, and the stars than any of them could have imagined.
