"Sign by Friday, Miss Calloway, or find another miracle." Nora Calloway had seventy-two hours, forty-seven dollars, and a medical bill for $312,000. Her brother Danny needed surgery or he would never walk right again. She had no options left. Then Ethan Weston — Manhattan's coldest billionaire CEO — made her an offer she couldn't refuse. Marry him for one year. Keep the secret. Play the role. In exchange, her brother lives. Simple. Clean. Just a contract. Except nothing about Ethan Weston is simple. He is controlled, ruthless, and completely shut off from anything that looks like feeling. He plays piano alone at midnight and stops the second anyone gets close. He wrote eight house rules and typed them. He says her name like it costs him something. And Nora — who came into this arrangement promising herself she would feel nothing — is failing that promise one small moment at a time. When the truth finally surfaces — that Nora was never his first choice, that her name replaced another woman's on that contract — everything they have quietly built together shatters. She was the replacement. She was never supposed to matter. So why can't either of them let go?
