Finn is fifteen and in high school. Seth is nineteen and looking for a job. From the moment they meet, they are instantly attracted, and the more time they spend together, the more fun they have. But Finn's parents forbid her to see Seth. They say Seth's too old and that he will be too demanding. Finn argues that she's old enough to handle herself, and she's sure she is.

Up in Seth's attic room, Finn and Seth begin to meet secretly, and as their feelings for each other deepen, Seth wants more. Finn is sure of her love for Seth, but she doesn't know if she's ready for more than kisses.

It's a time of important choices for Finn: How can she convince Seth to wait until they're both more prepared? And how will she show her love for Seth while denying him what he says he wants?
