Cassie Newman is new to Northridge High. She moved from California to Utah, and is still adjusting to a new life with new friends, like her friend Stuart Lee. Cassie's little sister, Ivy, is just as annoying as ever. But when Annie Young, the bitchy popular girl, starts being nice to Cassie (and sort of nice to Stuart), Cassie starts to wonder why she always gets these butterflies in her stomach when Annie is around her.
