Leonel Crawford - the cold and dangerously powerful head of the Crawford family. Untouchable. Ruthless. A man no woman has ever been able to keep close. He's also her ex-fiancé's uncle. One impulsive proposal changes everything. "If you need a wife... marry me instead." "Honestly... we'd make a pretty good match."

On the night of my sister’s engagement party, my life officially crashes. Again. All because of one name on the invitation. Zachary de Sanctis. My sister’s fiancé. Fiona. My ex, the guy I punched in the face five years ago. Heir to the richest old-money family in Europe. And one tiny detail only God and I know: he’s the father of my twins. For the past five years, I’ve been hiding out in a little town in Oregon, working as the CEO of a IT firm while chasing two four-year-olds who look more like their father than me. Isaac and Isabella: two mini De Sanctis clones with the last name Gómez, razor-sharp mouths, brains that run too fast, and a talent for causing trouble exactly when I need peace. My family knows I came home pregnant and alone. They just never asked who the father is, and I never offered an answer. As far as they’re concerned, I’m still Arabella Gómez, the wild one who lost her way. I thought going to Fiona’s engagement party would just mean a few hours of fake laughing, then a quiet drive back to my glass-walled house in Oregon and two sets of blue eyes calling me Mommy. Until Zach walks into my parents’ living room holding Fiona’s hand… and his gaze stays on my face a little too long. He can’t find out about Isaac and Isabella. Fiona can’t find out her perfect fiancé was mine first. And my family can’t know what really happened five years ago. Hiding a scandal between two rich dynasties is one thing. Hiding two chaotic twins who are basically their father’s face copy-pasted? That’s the real nightmare.

“Give me one reason, Liv.” He stalked toward me, cornering me against the edge of the desk. “One good reason why I shouldn’t bend you over this desk and f*ck you senseless.” My breath caught. “This is wrong, Damon. So wrong.” I pressed my palms flat against his chest, trying to create space. “You’re my brother-in-law…” “Not yet, love,” he whispered, fingers curling around my waist possessively. “You’re still engaged to him, but the man you’ll be getting married to…” Two fingers slipped into my heat, making me gasp. “…is me.” I should’ve walked away. I should’ve resisted. But I couldn't forget what it felt like to be his. * Olivia have the perfect life. The perfect fiancé. Marcus is everything she thought she wanted—sweet, charming, dependable.

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.

“You’re getting engaged tomorrow.” My father said blandly as if he was talking about the weather. But that wasn't my problem. The problem is I’ve only met the girl once… and I don’t even like girls. No one knows I’m gay. Not even my father. So, the night before the big party, I did something stupid. I went to a bar. I got drunk. And I kissed a stranger. He was hot and dangerous in the best way. We had a one night stand. One night. That’s all it was supposed to be. Until the next day... when he walked into my engagement party. My fiancée turned to me and smiled. “Meet my brother.” I looked at him, frozen. And then he said, with a smirk— “Nice to meet you.” My heart dropped. This wasn’t just a one-night mistake anymore. Now, it’s the beginning of something dangerous... and maybe something real. Something I wanted.

Now trapped in a secret that could destroy everything, she’s forced to question what really happened and why it feels like more than just an accident.
