Prom Princess — Diana G. Gallagher

Spring is in the air at White Oak Academy, and the seasons aren't the only thing that's changing on campus! Everyone is buzzing with excitement over the first annual Spring Fling dance, which will include a vote for Prom Prince and Princess!

Ashley decides to run for Prom Princess -- but when someone sabotages her chances, Mary-Kate instantly knows who is to blame -- their nemesis, Dana Woletsky. Mary-Kate confronts Dana -- only to find out that she is totally innocent! Mary-Kate and Ashley feel terrible about blaming Dana, so to make it up her they vow to help her win the contest.

Can Mary-Kate and Ashley turn snooty, obnoxious Dana into a gracious, popular beauty queen? Or will the real cheater take home the crown?
