Since Mia's the brand-new crown princess of Genovia, indomitable dowager princess Grandmere arranges a national primetime interview for her. With just a few innocent remarks, Mia manages to enrage her best friend Lilly, practically get one of her teachers fired, and alienate the entire country of Genovia. (Population 50,000, but still!)

She's just a New York City girl living with her artist mom. News flash: Dad is prince of Genovia. (So that's why a limo always meets her at the airport!) Downer: Dad can't have any more kids. (So no heir to the throne.) Shock of the century: Like it or not, Mia is prime princess material.

Never before has the world seen such a princess. Nor have her own subjects, for that matter. Mia's royal introduction to Genovia has mixed results: while her fashion sense is widely applauded, her position on the installation of public parking meters is met with resistance.

Things are looking up for Mia: she's the newest staffer on the school paper, and her miraculous completion of freshman algebra is just around the corner. Plus she's about to get a new baby brother or sister. Could things possibly get any better?

Princess for president. Student body president, that is. It's all the fault of Princess Mia's power-mad best friend and campaign manager, Lilly, who nominates her in the first place. This is not how Mia imagined kicking off her sophomore year, even if Grandmère thinks ruling her high school makes good practice for ruling Genovia someday.
