The Princesses of Iowa - M. Molly Backes I swear there is some formula out there that goes like this for some of these YA books.

1. Girl is popular
2. Girl does something stupid, friends get mad at her
3. Girl sees life as an unpopular person
4. Girl discovers what a bitch she was
5. Girl starts to fall for "nerd"
6. Girl's friends/boyfriend start accusing her of changing
7. Girl discovers life on the other side isn't bad
8. Girl messes up and alienates "nerd"
9. Girl realizes she is in love with "nerd" and chases after him, in the rain, kissing him and ending the book
