Arthur awakens from a hidden past as the final subject of a secret military experiment, imprisoned in ice after officials feared the weapon they had created. Offered a chance to uncover his stolen history, he accepts a ninety day assignment guarding Sophia Windsor. Sophia leads Helix Biotech and has developed Sanctum, a breakthrough treatment capable of destroying cancer cells. Her discovery puts her in the crosshairs of the ruthless Blake dynasty, whose pharmaceutical fortune depends on controlling her work. Criminal crews, contract killers, and altered human weapons close in from every side. What begins as a bargain for Arthur becomes something far more personal. To keep Sophia alive, he must confront the forces that erased his life and fight for the future neither of them believed possible.
