One contract. One marriage. One secret worth more than a hundred million dollars. Amelia Hart thought she had lost everything when her father died. His company was drowning in debt, their family home was about to be seized, and the people who once called themselves her father's friends were already waiting for the family empire to collapse. Then, at her father's funeral, a stranger appeared. Adrian Black. The ruthless billionaire CEO of Blackwell Corporation. A man Amelia had never met. Yet he knew her name. He knew about her father's debts. And most disturbingly, he knew about a promise her father had made before his death. Adrian offers Amelia an impossible deal. He will save her family's company and erase its $100 million debt—but only if she becomes his wife for one year. Amelia refuses. Until Adrian shows her the final document her father signed. There is no way out. With her family's future at stake, Amelia reluctantly signs the marriage contract. But Adrian has one condition. She must never ask why he chose her. At first, Amelia believes the marriage is nothing more than a business arrangement. She moves into Adrian's luxurious mansion, enters his world of billionaires and power, and discovers that being the wife of one of the country's most powerful men comes with rules she never agreed to. Adrian is cold, controlling, and impossible to understand. Yet behind his ruthless exterior are moments Amelia cannot explain. The way he protects her when no one is watching. The way his expression changes whenever she mentions her father. And the way he looks at her as if he has known her for far longer than he claims. Then Amelia discovers a locked room inside the mansion. Inside is an old photograph. Her father is standing beside Adrian's family. And between them is a little girl who looks exactly like Amelia. But the photograph was taken three years before Amelia was born. Suddenly, her marriage no longer feels like a business deal. Someone has been hiding the truth about her entire life. And Adrian may know more than he is willing to admit. When Amelia finally discovers a recording left behind by her father, she learns a devastating secret:The man who raised her may not be her biological father. The $100 million marriage was never about saving a company. It was about bringing Amelia into Adrian's world. But why? What happened between their families twenty years ago? Why was Amelia's identity hidden? And why does Adrian seem determined to protect the very woman he originally intended to use? As secrets unravel, Amelia must decide whether she can trust the man she was forced to marry. Because sometimes the most dangerous person in your life isn't the enemy standing against you. It's the person standing beside you, promising to protect you. He married her for revenge. She married him to save her family. Neither expected to fall in love. And neither knew that their marriage would uncover a secret powerful enough to destroy them both.
