Elena Hart thought she knew what she was signing up for when she agreed to work for billionaire Adrian Castellan for six months to pay off her brother's debt. She was wrong. Adrian is ruthless, calculating, and impossibly cold. He’s the kind of man who built an empire by crushing anyone who got in his way. But something about him doesn't add up. The way he watches her like he's waiting for her to remember something. The locked room on the third floor she's forbidden to enter. The photograph she finds hidden in his study of a woman who looks exactly like her. When Elena demands answers, Adrian makes her an offer she cannot refuse: Stay for one year instead of six months, and he'll tell her everything. Leave now, and she'll spend the rest of her life wondering what he was hiding. But the truth is more dangerous than Elena could have imagined. Because Adrian Castellan is not just a billionaire with secrets. He's a man who's been waiting five years for her to come back. And he'll do anything (lie, manipulate, destroy) to make sure she never leaves again. Even if it means she'll hate him when she finally remembers why.
