High school senior Mary Jane Ettermeyer has been the good girl for a long time. To date, she's proud to say she's been able to keep her pledge of abstinence (not that anyone has challenged it). But when the cutest guy in school starts flirting with her, she suddenly finds herself crazy in love. Even though her inner Plain Jane is telling her he can't possibly think she's cute, her inner Sexy M. J. is questioning her vow to keep herself pure until marriage. Not to mention that hot Jackson House shouldn't even be talking to her, because he already has a girlfriend! There are a ton of good reasons why she should never speak to Jackson again, except that every time she sees him, all of her resistance seems to melt away. . . .
