She needed money to save her family. He needed a wife to fulfill a contract. Isabella Hart never imagined that saying "I do" to a stranger would change her life forever. Ethan Kingsley, a cold and powerful billionaire, offers her a one-year contract marriage with one simple rule: never fall in love. But living under the same roof blurs the lines between pretense and reality. As hidden secrets, dangerous enemies, and painful betrayals threaten to tear them apart, Isabella discovers that some contracts can bind two hearts in ways no one expects. Will they walk away when the contract ends, or will love prove stronger than the deal that brought them together?
