"Zeke, was I just a substitute?" I asked, my voice trembling. "All these years, was I nothing but a replacement?" But then again, he remained silent. And I took that as a 'yes' to my questions.

"… Are you planning on making me someone else?" I asked, my bottom lip trembling slightly as I began to realize what I had gotten myself into. "Too many questions." He stared straight at me, and then his lips spread in a sly smirk, "You are right, anyways. You are no longer who you used to be. What is your name?" "Persephone Walters." I told him with a hidden plea in my voice. Please don't make me disappear… "From now on, that person is dead. You will now be my girlfriend, and wife-to-be, the elegant Kassandra Aaron." ______________________ She’s a mechanic. He’s one of the richest CEOs in the state.

“Do you know why he married you?” Her smile was cruel, her blind eyes staring straight through me. “Because you’re wearing my eyes and he promised to protect them.” My breath caught, but she wasn’t done. She leaned closer, as she whispered in my ears “Face it, Olivia. You’re nothing but my replacement.” Leonard always seemed like the perfect husband, until she woke from her five-year coma and shattered my world with the truth. He married me for my eyes.

But in a game where love and vengeance collide, the most dangerous twist isn’t my fury it’s the fire that never died between us. He made me a substitute. Now, I’ll make him suffer.

Mia Scott had one rule: never let anyone know who she really was. For years she lived without the Scott name, the mansion, or the empire, just a quiet apartment and a man she believed loved her for exactly what she showed him. She was wrong about the man. Wrong about her best friend. Wrong about everything she thought she had built. One humiliating night at a bar. One ruined suit. One cold marriage alliance with Ethan Brook, the most powerful CEO in the country and the most emotionally unavailable man she has ever met. She didn’t want him. He didn’t want her. They both had rules. Then she walked into her father’s company as the hidden daughter nobody expected, rebuilt herself from the inside out, and started winning battles everyone assumed she would lose. And somewhere between the boardroom rivalries, the betrayals, the connections neither of them planned, the rules stopped working. Ethan Brooks doesn’t do love anymore. His wife is dead and the guilt lives in his chest like something permanent. He never expected Mia will be the one person who could reach it. From being betrayed to boardrooms.
