"A Byron Preiss Book."

Gully Foyle, Mechanic's Mate 3rd Class, is the only survivor on his drifting, wrecked spaceship. When another space vessel, the Vorga, ignores his distress flares and sails by, Foyle becomes a man obsessed with revenge. He endures 170 days alone in deep space before finding refuge on the Sargasso Asteroid and then returning to Earth to track down the crew and owners of the Vorga. But, as he works out his murderous grudge, Foyle also uncovers a secret of momentous proportions.
