Dishonored Recon Marine Walker Jameson has pulled off an inconceivable escape from California's Terminal Island Penitentiary—leaving behind a cup of mouthwash, a strand of dental floss tied to one cell bar . . . and the dead body of a sadistic killer.

Deputy U.S. Marshal Tim Rackley must solve the riddle of an impossible prison break—and follow a trail of corpses to an escapee whose lethal skills, ice-cold cunning, and single-minded determination make him a mirror image of Rackley himself. But the more the elite manhunter learns about his quarry and the death of Jameson's sister—a suicide that's looking suspiciously like murder—the more uncertainty creeps in. Walker is a man on a bloody mission of his own, one that propels him and his pursuer into the dark, deadly underworld of corporate corruption, cheap lives, and murderous greed. And vengeance and justice may lie somewhere Rackley never anticipated . . . because a little boy's future hangs perilously in the balance.
