Twelve-year-old Lizzie is starting seventh grade. Known as "Lizzie the Lizard" by her classmates because she likes to read, write poetry, and wear long, flowing dresses. Lizzie decides to change her image to fit in with the popular crowd. She wears jeans, hides her math expertise, and giggles on cue. It all works until her math grades begin to plummet, and eventually, Lizzie must gain the self-confidence she needs to be herself.
