For two years, I was the perfect shadow of another woman. I wore the silk robes Brittain Austin bought, styled my hair exactly how he liked, and spoke in a voice pitched half an octave higher than my own. I was a placeholder, a living statue in a minimalist Manhattan penthouse, waiting for a man who looked at me but never actually saw me. Everything shattered when a news alert flashed on my phone: "Caryn Newman Spotted at JFK." The original was back. The woman I was hired to mimic had returned to claim her throne, and my secret two-year contract as her stand-in was set to expire in three days. Brittain didn't even give me the courtesy of a phone call. While he was supposed to be on a business trip, photos surfaced of him shielding Caryn from the paparazzi, his hand on her waist with a tenderness he never showed me. When I walked into his office to return his keys, he didn't look guilty; he just looked annoyed. He pulled out a checkbook and asked, "How much for the hurt feelings?" When I refused his money, he coldly ordered his assistant to freeze every one of my accounts before I even reached the elevator. I stood on the sidewalk with zero dollars, realizing that to him, I wasn't a partner—I was just an expired lease. I had spent two years erasing my soul to fit into his world, only to be tossed out like trash the moment the real thing came home. But Brittain forgot one thing: before I was his doll, I was an actress. I pulled my secret weapon from under the bed—a notebook and a raw film cut he never knew existed. I called my agent and launched a high-profile "showmance" with my co-star that set the internet on fire. As I blocked Brittain's number and moved into a dusty apartment in Queens, I realized the show wasn't over. For the first time, I was the leading lady.

He had taken everything from me-my love, my family, my dignity. He thought he had broken me. But he only forged me into a weapon. Now, I'm back. And as the new majority shareholder of his company, I'm here to make him pay for every last sin.
