Cobra warriors, surgically implanted with an arsenal of covert weaponry, are the most dangerous guerilla fighters humanity has ever produced. For Jin Moreau Broom, the war is the culmination of a lifetime of Cobra service. But it is also the height of danger for herself and her family as they struggle to survive a war that none of them ever expected to see.

The Troft invasions of Qasama and the Cobra Worlds has had at least one result: it has turned long-time antagonists into uneasy and unwilling allies. As the aliens battle to consolidate their conquered territories, a small group of Cobras and Qasaman Djinn work together to create a victory that will rock the invaders to the core, a victory designed to bring other Troft demesnes into the conflict on the humans' side. Now one young Cobra must forge a new political order as a devastating alien enemy strikes—an enemy more deadly than any humanity has ever faced.
