She said yes to the cold billionaire because her family needs the money. He said yes in order to use her. Neither of them expected him to wake up from coma three days later not remembering her at all. But that's when the real game begins. Aria thought she understood the rules: marry the cold billionaire, get through one year, walk away with her family saved and Rich. Simple. Transactional. Safe. But she was wrong about everything. When Casian doesn't recognize her after his accident, when his sister goes missing, when someone starts texting her secrets that could destroy them all, Aria realizes this marriage was never about saving her mother. It was all about saving him. But from what? From whom? And most importantly—can she trust anything he tells her when she discovers he was watching her long before he ever asked her to marry him?
