My stepsister was lying under my husband. Watching them together made my blood boil, and I wanted to destroy them both right at that moment. To everyone else, my marriage seemed perfect. My husband acted like he adored me, giving me expensive gifts and treating me like a queen. But I didn't realize those gifts weren't just for me. He was also giving them to my stepsister, who was secretly his mistress. Overwhelmed by emotion, I made an impulsive decision. Instead of screaming at them when I caught them, I turned to Shane, my husband’s younger brother, and slept with him. I had no idea that one choice would lead to such a complicated mess.

He takes her innocence in the locked back room while she begs him to keep it secret. She’s still married. He’s still family. And neither of them can stop.

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 Instagram: @authorpria for exclusive teasers, sneak peeks, and book updates.
