Scarlet’s world shattered the night she discovered her husband in her bed with her own sister. The betrayal was brutal. The humiliation, unforgivable. And what hurt the most? Neither of them felt a single ounce of remorse. Within months, her husband divorced her and married the very woman who helped destroy her life, her sister. They thought she would break. They thought she would disappear quietly. They were wrong. Ryan Marchetti—cold, calculating, and dangerously powerful, has spent years waiting for the perfect chance to destroy his business rival. Marrying that rival’s ex-wife is the ultimate move. Strategic. For Scarlet, marrying Ryan isn’t about love. It’s about revenge. A calculated alliance. A public statement. A promise that she will rise from the ashes they left her in. Together, they become the scandal that shakes empires. But revenge is never simple. Because behind Ryan’s icy control lies a secret, one tied to her past, to her ex-husband, to the very marriage that ruined her life. A truth so explosive it could unravel everything she thought she knew. Was she just a pawn in Ryan’s war from the very beginning? Or is the man she’s slowly falling for capable of betraying her too? In a game fueled by vengeance, power, and buried truths, Scarlet must decide: Will she let betrayal destroy her again… Or will she risk her heart for the one man who might truly love her?

"Get off me, you moron!" I shouted, pushing at his chest as he pinned me against the wall. His lips crashed down on mine with unexpected force. His kiss trailed to my neck, roaming across my skin until weakness washed over me. When his hand squeezed my breast, clarity jolted through me and I shoved him away with all my strength. "No! This is wrong!" I restrained. "My mind says the same, but why does it feel so right? Tell me why I can’t get you out of my head. Why all I can think about is f**ck*ng you!" His voice cracked with agony, lips still burning against my skin. "We’re stepsiblings. This is so wrong!" "We’re not real siblings, we share no blood at all!" He pulled back, his eyes blazing with emotion. "Even so, it’s still wrong!" "Then let it be wrong. I don’t care anymore." He kissed me hard again before his lips moved back to my neck. __________________________________ When Elyssa’s mom married wealthy Greg Almendarez, their modest life transformed into one of glitz and privilege.

On the night of my engagement party, I found my fiancé with his hands in my sister’s hair. I thought the betrayal ended there. I was wrong. Minutes later, Ethan stood in front of both our families and announced that he was in love with Ava. My sister. While everyone rushed to comfort them, I became the villain for refusing to smile through my own humiliation. Then Damien Black walked into the room. Powerful. Untouchable. The one man Ethan feared. Before the night ended, Damien handed me a contract. One year. One marriage. One chance to save my father’s company. All I had to do was become his wife. I should have said no. Instead, I signed. Now my ex can’t stop watching me. My sister can’t stop competing with me. And the man I married keeps protecting pieces of me I thought nobody noticed.

When I turned 18, my mother married my stepfather, a retired mafia kingpin, and I moved with her into a luxurious mansion. Just when I thought my life was heading toward happiness, my stepbrother, the new mafia boss, stormed into my life. He was like a devil, with delicate eyebrows, a high, sharp nose, and lips that were always tightly pressed together beneath a cold expression. Every time our eyes met, I felt a chill run through me, making it hard to breathe. I tried my best to avoid him, but he had no intention of letting me go. “My stepsister, from the moment I first saw you, I knew I couldn’t let you go. You can’t escape—you’re destined to be mine.” I stared into his possessive eyes as his body pressed down on mine. “No, you're my stepbrother, we can't……"

I didn’t choose this life. I didn’t choose this house. And I definitely didn’t choose my stepbrother. When my mother marries the richest man in New York, I’m dragged into a world I heavily despise—a world of luxury, lies, and Lucian Castillo. He’s arrogant, rich, and cruel. He never misses a chance to remind me how much I don’t belong. We hate each other. Or at least, we’re supposed to. Because with every passing day, the hate only grows…along with an emotion I never thought I’d feel for him. I swore to hate my stepbrother. But caught between unforeseen passion, temptation and buried secrets, I’m no longer sure that’s possible.
