"Look at the target, Gabe," Derek hissed, his voice a low vibration that settled in my bones. "Imagine it's my heart. Imagine you are finally putting me out of my misery." I was trapped between the cold metal of a gun and the burning heat of his body. My finger trembled on the trigger, but I couldn't pull it. My name is Gabriel. To the world I am the nerdy quiet university student. To Derek Miller, I am his toy. He found my secret sketchbook, page after page of his naked body drawn with obsessive detail. Now, he uses those sketches to keep me on a leash blackmailing me whenever he wants a taste of my dignity. But the nightmare was only beginning. When my religious mother announced she was marrying Derek’s billionaire father my world shattered. My bully wasn't just a ghost from campus anymore, he was my stepbrother. We share a room. We share a bathroom and now my body. He is everywhere I breathe. He claims me. He insults me. He treats me like trash. And the sickest part? I have realized I loved it rough. Our obsessive love is impossible. My mother would disown me, the Miller name would be tarnished, and Derek’s tough love is starting to leave scars I can't hide. Just as I am about to break, a new guy enters the picture someone who promises to love me softly. Someone who doesn't smell like gin and danger. But in the dark world of the Millers, safety is a lie. Now I have to choose: Do I run toward a peaceful future, or do I stay with the devil I already know?
