The Pink Dress [EPUB ebook] 

A hurt leg kept Susan Stevens sidelined at the Halloween dance, and the flu ruled her out of the Christmas ball, but nothing can keep her away from the Peppermint Prom. Only a ninth grader, Sue is ready to make her Taft Junior High debut, and she’ll be wearing a perfect pink dress. The prom is as elegant as a fairytale, and it doesn’t take long for Sue to meet her prince. Dave Young is dashing, graceful, with a devil-may-care attitude that Sue cannot resist. He offers his hand, and sweeps her into a dance that will change her life forever. Soon, she and Dave are an item, and Sue is a certified member of The Crowd. But popularity brings new pressures, and Sue will find that beneath their peppermint smiles, her new friends have a sour side.
