She was off-limits. Until she wasn't. PIPER:I shouldn't want him. I shouldn't lie awake at night imagining how his hands would feel on my skin or how his mouth would taste against mine. But Christian Crawford has been my deepest, darkest fantasy since the moment I met him. I've tried to bury my feelings for my boyfriend's father.  I've tried to pretend that the chemistry between us was one-sided, but every time that cowboy looks at me like I'm already his, I forget who I'm supposed to be loyal to. He's the one man I should never touch, and I've never wanted anything more. CHRISTIAN:She's the one line I should never even think about crossing. She's too young, too wrapped in every kind of wrong. And my son's girlfriend. But Piper got under my skin the second she stepped into my world. Sweet, stubborn Piper, who's all fire, and a temptation I never saw coming. I told myself it was nothing more than a passing thought. But there's nothing passing about the way I watch her. There's nothing innocent about the way I want her. I know it's wrong. I know touching her would destroy everything. But somewhere between the guilt and the longing, I started falling for her. And now that I have... I don't know how to stop.
