One summer. One plan. Two boys. Jess's older brother's best friend - aka her giant crush - is staying at their house for the summer. She either has the best luck ever or the worst. This is her chance to show him she's not just his best friend's shy little sister anymore. But he's a college boy. And she's...her. Just turned eighteen. Just graduated high school. Just way too innocent for him. Jess is a virgin. She's never been ashamed of that, except now it's holding her back from what she wants. Her lack of experience is wildly obvious, a repellant for boys who want a partner who knows what they're doing. So the only way to get the boy she really likes to notice her is to ask the boy she really hates to show her how to be, well, less innocent. And she hates Benjamin Oliver. Loathes. Despises. Can't stand the sight of his stupid-hot face. He's her frenemy throughout and through, and a player, so not the kind of guy she'd ever seriously consider. But she needs his help - and he's actually willing to give it. All she has to do is promise him one little favour...
