Cobra Slave

the long version

"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."--Provided by publisher.
