When a government black ops program marks her for death, Mary, a decorated Marine turned enhanced super soldier, narrowly survives an assassination attempt in her Miami high-rise. Outfitted with experimental armor and genetically altered through a classified initiative called Project Hellhound, Mary escapes and disappears into the shadows. Hunted by the very military that built her, she activates an old contingency plan, reconnecting with Travis, an underground hacker, to uncover why she's suddenly a threat-and discovers she's not the only asset the government created. The truth is devastating: General Ryland Monroe, architect of the program, has gone rogue with a secret council, using false-flag terror attacks and weaponized super soldiers to dismantle global order and rebuild it in his image. Mary learns of Nyx, her genetically engineered clone-a ruthless, fully obedient version of herself-designed to hunt her down and replace her. With the help of her former flame, Red Phoenix, a feared Ghost Operative living off-grid, Mary arms up and goes on the offensive, launching a guerrilla war against Monroe's facilities, liberating test subjects, and exposing the global conspiracy to the world. As cities erupt in chaos and sleeper agents activate across the U.S., Mary leads a brutal assault on Blacksite Omega, the final Helix stronghold. After killing Monroe in a devastating face-to-face battle, Mary must face Nyx in one last fight-clone versus original, weapon versus warrior. She emerges victorious, but disappears into the wilderness, presumed dead. As the world reckons with the truth, rumors persist of a woman in black armor watching from the shadows, waiting for the next threat. Because Mary was never just a weapon, she became the reckoning.
