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.

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. The problem is that Damien Black is hiding something. And every day I spend with him makes me less certain that our marriage was ever supposed to be just a contract.

My sister's husband smirked. "You can call me the devil, but I know what I want." My eyes nearly popped out of their sockets as I stared at Damon's nûde body. This felt so wrong. He was my brother-in-law. "What do you want?" I breathed. Damon took a step closer, his gaze dark with intent. "You. I want you, Ava. I want to own you, and I’m done watching Walter hover around you like he has a chance. You belong to me." ~~~~~~ After a devastating breakup, Ava finds herself homeless in New York. Her older sister, Adrianna, offers her a place to stay, but moving in with her turns out to be the biggest mistake—or temptation—of her life. Adrianna and Damon’s marriage seems perfect on the outside, but cracks are beginning to show, and Ava gets caught in the middle. Damon is dangerous, possessive, and alluring. Despite every effort to resist, Ava finds herself drawn to him in ways she shouldn't be. Torn between loyalty and an undeniable attraction, Ava struggles against the forbidden pull of her sister’s husband. But when the tension between them becomes unbearable, one question remains—will she give in and damn the consequences? Find out in this gripping forbidden romance.

Three months, she was supposed to live with her sister's family for three months but how will she survive living in the same house with him when she harbors those nasty thoughts? How will she survive living in the same space with him when he was the reason she left for Paris three years ago? How will she hide the love and lust she has for her sister's husband?

Her back hit the cold wall before she could even breathe. Damian’s hand slid to her jaw, tilting her face up to his. His voice was a low, trembling threat. “Do you feel what you’re doing to me, Aria?” Her heartbeat stuttered. “You’re my sister’s husband…” “Exactly,” he whispered. “That’s why I shouldn’t want you.” He leaned closer, his breath brushing her lips. “But wanting you is all I’ve done… every damn day.” ************************* Aria Hale has spent her life unseen, ignored by her father, used by her sister, and taught that her feelings don’t matter. But everything changes the day she moves into her sister’s place… the same home ruled by Damian Cross. Thirty-six. Billionaire. Cold. Married to her sister. And quietly, obsessively fixated on Aria. He watches her too long. Stands too close. Speaks too softly for a man with no heart. He looks at her like she’s the only warmth in his frozen world. Aria tries to avoid him. Tries to reject him. Tries to pretend she doesn’t feel the air tighten when he enters a room. But Damian does not let go. He corners. He interferes. He destroys anything that dares approach her. Because wrong or not, forbidden or not— he has already decided she belongs to him. And when the truth behind his obsession finally comes to light… Aria will learn that some desires, once awakened, are impossible to escape. ******************************* Follow me on social media.
