In a world ruled by the most powerful cartel on earth, Onyx Noir is a man feared for his brutality, short temper, and absolute lack of mercy—someone who reacts first and never forgives twice. When a corrupt mafia underboss makes the fatal mistake of offering his stepdaughter as payment for a debt, he unknowingly draws the attention of a man who doesn’t accept human beings as currency. As Onyx destroys everything tied to the debt, he enters the estate expecting a final execution—only to notice a silent girl drifting through the chaos like she’s learned how to disappear from life itself. What begins as a punishment for disrespect becomes something far more dangerous, as Onyx is forced to confront the one thing his violence has never accounted for: someone who shouldn’t have survived the world she was born into, and a connection that could unravel the very empire he built.
