He made me pretend to be his sister so he could marry another woman. He didn’t know I was carrying his child. I spent four years as Daniel Lancaster’s hidden wife. Controlled. Ignored. Never loved. The night I planned to tell him I was pregnant, he announced his engagement to another woman. A billion-dollar deal. And I had a new role. His sister. I agreed. Not because I was weak. Because I had a plan. We had a deal. I keep his secret. I wear the mask. I smile at his new fiancée. In return, I get my freedom. School. Work. A life of my own. Now I live in his house and watch him fall apart while my belly grows with his child. But Daniel Lancaster isn’t the only one hiding secrets. Because the woman he pushed aside may not be ordinary after all. One invitation. One family dinner. One shocked stare from a billionaire who swears I look exactly like the daughter his family lost twenty-five years ago. Now powerful people are asking questions nobody wants answered. Who am I really? And why does the richest family in the country look at me like I belong to them? Let them underestimate me. Let him regret me. Daniel Lancaster wanted a wife who would obey him. Now he gets to watch the woman he broke become the lost heiress who can destroy everything he built.
