Bogie, the sentience within Jack's battle armor was fighting a life-and-death struggle, and it was Jack who might ultimately pay the price for the alien's survival. The Thraks themselves had learned new tactics to turn against the Knights, and even within the Dominion Empire there were many intent on Jack's ruin.

Then a new player appeared in the games of conquest. A mysterious race from beyond the known worlds whose spaceships roved the starways, bringing annihilation to human and Thraks planets alike!
