I was raised in the shadows, my mind weaponized by an abusive family who saw me as nothing more than a free accountant. When my half-sister flees her arranged marriage to Dante Moretti—the lethal, possessive head of the nation's most feared syndicate—my adoptive father gives me a choice: walk down the aisle in her place, or watch them pull the plug on my dying brother's life support. Stepping into Dante’s glass-and-steel fortress is a suicide mission. Dante is known for executing traitors without hesitation, his cold eyes hiding a mind that calculates every breath in the room. But on our wedding night, when he pins me against the silk sheets demanding to know why my pulse isn't racing, I don't flinch. I look the monster in the eye and make a deal with the devil. I have ninety days before the international syndicate gala, ninety days before my real identity is leaked to the five families. My plan is simple: hack Dante's offshore networks, steal fifty million dollars to secure Leo's treatment, and disappear into thin air. But simple plans disintegrate under Dante Moretti’s touch. As I use his resources to secretly destroy the family that sold me out, Dante begins to shadow my every move. His suspicion turns into a dangerous, dark obsession. Every touch is an interrogation; every kiss is a territorial claim. He thinks he's breaking down my walls to find a secret traitor, but he doesn't realize he's unlocking the queen beside him. When the real heiress returns and my countdown hits zero, Dante doesn't pull his gun on me—he turns his entire empire against the world to keep me locked in his arms.
