Being the new girl is tough, just ask sixteen-year-old Rio Jones. A New York transplant, Rio has no clue how she's going to fit in at her fancy new private school in Southern California. Plus, being late, overdressed, and named after a Duran Duran song doesn't make the first day any easier for her.

Then Rio meets Kristi. Beautiful, rich, and a cheerleader, Kristi is the queen bee of Newport Beach. And Kristi isn't friends with just anyone, so Rio is thrilled when she's invited to be part of the most exclusive, popular clique. Of course, like any club, Kristi and her friends have rules: Always smile (even if you don't mean it), always dress cute (and never repeat outfits), and always flirt (but only with jocks, preps, and rich college guys).

At first Rio is having a great time, but as she becomes more immersed in this jet-set crowd, she figures out there is one last rule that her new friends forgot to mention: Don't cross Kristi . . .
