Grace Hill, a “holy” choir girl trapped in a sadistic, greedy family that murdered her mother and imprisoned her life, meets Mason Richter, a ruthless mafia heir who sees through her angelic mask to the fury beneath. She uses him as her blade—crashing weddings, hacking evidence, and dismantling the empire that destroyed her—while he falls irreversibly in love. Bound by shared darkness and a hunger for justice, they become each other’s accomplice and salvation. As betrayal, sacrifice, and blood ties threaten to tear them apart, Grace must choose between freedom alone or trust in the one man who would burn the world for her—and Mason must prove he is not just her weapon, but her home.
