Best Step Brother Romance Books

I made a mistake that could ruin me. I fell for a man I should’ve feared. At sixteen, I was drawn to him like a moth to a flame. Gianni Rossetti. My best friend’s father. A ruthless billionaire. A cold-blooded villain. A man twice my age, who could destroy me with a single look. For years, I was nothing to him—a silly girl with a foolish crush. But I couldn’t forget those icy blue eyes, the way his presence made the world feel small and dangerous. By the time I was twenty-one, I knew I should’ve walked away, left my fantasies behind. But then, one night, Gianni noticed me. And my world turned upside down. He didn’t just see me—he ‘claimed’ me. Every forbidden fantasy I’d ever had, he brought to life. He touched me, possessed me, made me feel things that shattered everything I thought I knew. With him, I wasn’t just a woman; I was ‘his’. But the deeper I fall, the darker it gets. Gianni’s world is filled with secrets, shadows that whisper of violence and betrayal. His past is more than just a dark history—it’s a deadly curse that threatens to consume us both. I knew he was dangerous, but I never imagined this. Now I’m trapped, caught in a web of desire and deceit, and the deeper I go, the harder it is to find my way out. But the worst part? I’m not sure I want to escape. Not if it means losing him.
