Cobras: technologically-enhanced warriors bred to fight an alien menace no ordinary human can withstand. In times of war, the Cobras are necessary, yet in times of peace they are often reviled by those they have saved. Now the Cobras have resisted a second invasion of the alien Troft forces, and forced the Troft to a stalemate - and even converted some thoughtful Troft into uneasy allies against their kin. Yet all is not well in the human sector of the galaxy. A supposed sister empire, the Dominion of Man, threatens the Cobra worlds with what is, in effect, enslavement, as it moves to consolidate power over all the Cobra worlds. The plan on Aventine: to extort from the Moreau family the location of the home planet of a mysterious human ally that may be more powerful than the Dominion: the Qasaman empire! Meanwhile, Cobra Merrick Moreau is on a secret mission of his own to a world of humans enslaved by Troft masters. It is a world of barbaric cruelty where humans are slave chattel to Troft gamblers. There the Troft force whole villages, even children, into life and death struggles served up for Troft entertainment. New York Times numbered 1 bestselling author Timothy Zahn continues his Cobra SF adventure series with Cobra Slave, the first entry in a new Cobra saga, Cobra Rebellion.
