Sixteen-year-old Jess Parker survives by staying invisible. After nine schools in ten years, she's come to terms with life as a perpetual new girl, neither popular nor outcast. At Mt. Sterling High, Jess gets the chance of a lifetime: an invitation to join The Cinderella Society, a secret club of the most popular girls in school, where makeovers are the first order of official business. But there's more to being a Cindy than just reinventing yourself from the outside, a concept lost on Jess as she dives tiara-first into creating a hot new look.

With a date with her popular crush and a chance to finally fit in, Jess's life seems to be a perfect fairy tale. That is until the Wickeds--led by Jess's archenemy--begin targeting innocent girls in their war against the Cindys, and Jess discovers her new sisterhood is about much more than who rules Mt. Sterling High School. It's a centuries-old battle of good vs. evil, and the Cindys need Jess on special assignment. But when the mission threatens to destroy her new dream life, Jess is forced to choose between this dream realized and honoring the Sisterhood. What's a girl to do when the glass slipper fits, but she doesn't want to wear it anymore?
