Synopsis: From the back cover of the DAW Books first edition: Sand Wars. The Trakian invasion had swept from world to world, turning once fertile planets into vast, desert wastelands. To halt these world destroyers, the Dominion Empire sent it its finest warriors - the Knights. In their powered battle armor, the Knights had fought a valiant, last-ditch effort, slowly retreating along the starways, buying vital time for the Empire. And then as the Thrakian menace slowed to a halt, the last Knights found themselves abandoned to near certain death, or worse yet, to the possibility of a hideous betrayal by their own, alien-repaired battle armor. Yet in the midst of disaster, one Knight escaped - Jack Storm. And, after seventeen years of coldsleep on a derelict spaceship, Jack was rescued and returned to the worlds of the living. He was the last Dominion Knight, and he was about to embark on a one-man crusade of vengeance against the evil hidden in the very heart of the Empire!
