A wedding dress. A contract. A lie. Now two ruthless billionaires own a bride who was never meant to be theirs... I’m the devil Houston society whispers about—the man with too much money, too much power, and zero patience for liars. I was supposed to marry her sister. A calculated transaction, sealed with a contract and a carefully curated smile. But when the woman walking down the aisle isn’t the one I bargained for, I don’t stop the wedding. I see an opportunity. Isla Davenport is soft, bookish, untouched—and now mine. A pawn in her family’s dangerous game, handed over to settle their debts and clean their sins. But they didn’t count on me wanting to keep her. Or my business partner, Brennan, the criminal with blood on his hands and loyalty only to me. She thought she could survive one ruthless billionaire. Now she’s all we hunger for—innocent, defiant, dangerously irresistible. We’ll crush anyone who dares challenge our claim. Theirs to Possess is a dark, sinful standalone in the Titans secret society world. It features two obsessed, controlling billionaires, a forced marriage, a runaway sister, a morally gray antihero, an actual criminal, age gap, innocent heroine, forced proximity, and the ultimate possessive "touch her and die" energy. Because when we say “I do,” it’s forever.
