A New York Times Bestseller -- In an underground club, a high-ranking public official spends his secret nights indulging in exciting and depraved fantasies. It's the job of a seductive employee of the Dungeon to fulfill them. But she's playing a far more dangerous game -- one of blackmail, politics, and murder that reaches into the shadow world of the GhostWalkers, and the creation of a spectacular, one-of-a-kind new weapon of defense. But when a dictator makes his own catastrophic moves, the GhostWalkers have no choice but to bring in two major players -- a man and woman both driven by passion and revenge. Both expendable. Both with nothing left to lose.
