DELAINY: Cruel. Heartless. A mistake just waiting to happen. Knox Vaughn is the epitome of a bad guy. He is trouble in a sexually sinful package. I know it. They know it. Even he knows it. But this like a moth to a flame. I can't stay away even if I get burned. You know what they say, sinners are more fun. And this saint is a game changer. KNOX: Sweet. Innocent. Excellent student. Delaney Callahan is perfect, too perfect for me. Damn, she's too perfect for anyone. She's an angel, But with me she's playing with the devil. I'm the last thing a girl like her needs. And yet I can't keep my hands and mouth away from her. We're from two different worlds, Worlds that can't work. I'd do anything for her, But I can't be the SAINT she deserves.
