Until he abandons her on their wedding day for another woman. With their powerful families' alliance at risk, there's only one solution: Julian's older cousin. Adrian Kingston. A ruthless billionaire CEO. The feared heir to the Kingston empire. Cold, private, and completely uninterested in marriage. Isabella barely knows him. She doesn't want him. He doesn't want a wife. But when Adrian signs the marriage agreement and slides the pen toward her, he gives her one final choice. "Your choice." Heartbroken and desperate to protect her family, Isabella signs. Now she's married to a stranger. They may share a last name, a mansion, and a marriage certificate, but Adrian makes one thing clear: he will never pretend to be Julian. Yet the more Isabella discovers about the man behind the cold reputation, the more she begins to wonder if marrying a stranger was the worst mistake of her life... Or the beginning of something she never saw coming. But what happens when the man she never chose becomes impossible to escape?
