He was the last man she would ever marry. But when twenty-four-year-old Elena Hart walks into a hotel expecting to meet the man who promised to save her family from financial ruin, she discovers the truth far too late. The man waiting for her isn't her father's business partner. He's Damien Blackwood-the ruthless billionaire who destroyed her father's company. Her family's sworn enemy. And the man Elena has spent years learning to hate. Damien offers her an impossible deal: marry him for one year, and he'll erase her family's debts, protect her younger sister, and give her father a chance to rebuild everything he's lost. Elena refuses. Until Damien shows her something that changes everything. A secret that could destroy her entire family. With no other choice, Eleana becomes Damien Blackwood's wife. But their marriage comes with rules. Don't fall in love. Don't ask questions. Never enter his locked room. And above all... Never uncover the truth about the night Damien's mother died. Elena intends to follow every rule. Until she discovers that her cold, merciless husband isn't the monster everyone believes to be. And the closer she gets to him, the more dangerous the truth becomes. Because Damien didn't marry Elena to save her family. He married her for revenge. And when Elena discovers the real reason he chose her... She may wish she had never said I do.
