How Does The Billionaire Fiance Change In Loving My Sister?

On her birthday, Giselle Macmillan receives a gift she will never forget. A video of her husband in another woman’s bed. In one brutal moment, her perfect marriage shatters. The love she believed in? A lie. The man she trusted? A stranger. Determined to walk away, Giselle demands a divorce… but Kennedy Macmillan refuses to let her go, tightening his grip like she’s something he owns. And then there’s him. Joseph Macmillan, Ken’s older brother. A billionaire, cold, ruthless, and untouchable. He doesn’t just want her gone. He’s determined to break her until she leaves Ken. But when Giselle’s father collapses from the shock and her husband disappears without a trace, the last person she expects steps in to save her was Joseph. The same man who’s been trying to drive her out of his brother’s life. Now Giselle is trapped between two brothers. One who won’t let her go, and one who might ruin her in ways she never saw coming.

--- This book is a sequel to "Marrying a Disabled CEO in my Sister's Place", but both stories can be read separately --- "My ex-fiancé cheated on me with my friend. Having his hot billionaire brother as my revenge partner seemed like a perfect plan, but... Maybe it went too far when I ended up in his bed.” Millicent Bianchi has always been known for being a good girl and a kind person. Revenge has never been part of her vocabulary. However, when she discovers that her fiancé had an affair with her friend, Millie decides that's going to change. This man's schemes are threatening her family and, for that, she's going to make him suffer. And, for that, she needs the most unexpected partner possible: Isaac Carnby, her ex-fiancé's mysterious and rude half-brother. This meeting of two revenges should be nothing more than a deal. But... "Tell me, Millicent." he murmured in her ear, until she was no longer able to contain her moan "Tell me you've never felt with him the way you feel with me."

One reckless night, I woke up in the bed of Ethan Van Horn — my sister’s ruthless billionaire fiancé. Now I’m pregnant with his child, and our powerful families have only one solution: force us to marry. He despises me for destroying his future. I hate him for treating me like the thief who stole what was never mine. Trapped in his luxurious penthouse, every cold glance turns into burning tension and every sharp word into forbidden desire. But the real danger isn’t the man I’m forced to call husband. It’s my sister — who will stop at nothing to take back the life and the man she believes are still hers.

"Marriage was never on Ariana's mind. Living a lifetime with a man, living in a dream house, having children who look like him, and a partner - these were all beautiful daydreams that other girls might entertain, but not her. Ariana decided to live a single life and enjoy the rest of her days alone. However, what if she was forced to step into the shoes of her twin sister, who disappeared right before the wedding, and marry a man she doesn't know? Although some people might consider her lucky to be married to a young billionaire who owns an international venture company, Ariana doesn't feel that way. So, will her marriage go according to plan because people are pressuring her? Or would the results be different?"

"Sign this. We're done." Aaliyah Monroe thought she’d found love with a rising billionaire, Henry Smith—until he blindsided her with divorce papers on their fourth anniversary, revealing her twin sister, Aurora, as his true love. Betrayed and cast out, Aaliyah drowns her fury in a nightclub, where she meets Orrin Hayes, a billionaire mogul who falls for her instantly. He offers her a deal– “Aaliyah, I’m smitten. You’re fire, and I want to burn. Marry me.” She froze as her heart tripped. “What?” “Not for love, not yet,” he said with his eyes glinting. “A deal. You want revenge on Henry and Aurora? I’ve got the power to crush them. Marry me, and I’m yours—my money, my connections, my everything. We’ll make them beg.” She stared, the whiskey clouded her head but not her judgment. The idea was insane, but it lit a spark. Henry’s face on that stage and Aurora’s smirk—they deserved to fall. And Orrin? He was a weapon, wrapped in charm and danger. “You’re serious?” she asked, testing him. “Dead serious.” He took her hand into his, gently. “I’m half in love with you already. Say yes, and we’ll shake the world.” She laughed, the sound was shaky but real. “You’re crazy. But… okay. Yes.” Aaliyah agreed. But there was one thing she was yet to inform this charming yet mischievous Billionaire suggesting marriage to her– she's carrying her ex husband’s child. Will she successfully use him to climb the ladder and get her revenge despite having a child for her ex-husband? Or will a second chance in love surface?

I saved Ethan's life when we were children but he always believed it was my younger sister who rescued him. From that day on he loved her. Then everything changed. After an accident left my sister unable to walk everyone blamed me for what happened even Ethan. Before long, my sister disappeared without a trace leaving me alone to carry the guilt and hatred. Because my sister and I look almost identical... Ethan drunk and broken mistook me for her one night. By the time he realized the truth it was too late as he forced me into a marriage swearing he would make me suffer for ruining the woman he loved. For years I lived beside a man who despised me. Then my sister came back healthy and beautiful and determined to take Ethan away from me. She demanded a divorce and Ethan didn’t stop her. I walked away with nothing except the divorce papers in my hand and the secret I carried. While they built the life they wanted I built myself from nothing. Years later, I returned as the owner of a powerful company no longer the weak woman they once knew. That was when Ethan finally discovered the truth. I had been the one who saved him all those years not my sister. But now the question remains… Can love survive betrayal, lies and a lifetime of secrets?
