The original Princess Diaries series sold over five million copies in the US (15 million worldwide), spent 82 weeks on the USA Today best sellers list, and inspired two beloved films.

Olivia Grace Clarisse Harrison has always known she was different. Brought up by her aunt's family in New Jersey, book-and-music-loving Olivia feels out of place in their life of high fashion and fancy cars. But she never could have imagined how out of place she really was until Mia Thermopolis, Princess of Genovia, pops into her school and announces that Olivia is her long-lost sister.

Olivia is a princess. A dream come true, right? But princesses have problems, too.
