"You can ask one thing," he told her. "Choose wisely." "Why are you doing this?" He met her gaze, his voice calm and merciless. "Because I want a child, and I want nothing to do with the mother once it is born. You will live in my house, follow my rules, and leave when it is over. You get your money, and I get my heir." He needed a womb. She needed $250,000. For Isabel Manor, agreeing to become a surrogate for billionaire Isaac Dun was supposed to be a simple transaction. Save her brother, carry the child, and walk away with no strings attached. But Isaac is not a man who does anything halfway. Cold and controlling, he keeps her close and under his watch, turning a contract into something far more complicated. What begins as a business arrangement slowly shifts into something neither of them expected. The closer they get, the harder it becomes to remember the rules. She was never meant to stay. He was never meant to care. But when feelings begin to grow and the past threatens to tear everything apart, the line between obligation and desire disappears. When the contract ends, will she still be just the woman who carried his child, or the one he cannot let go?
