The one and only Mia Thermopolis is back and ready to reign! Celebrate the 20th anniversary of Meg Cabot's blockbuster series in royal style--with all-new middle grade editions of the first three books!

Mia Thermopolis is pretty sure there's nothing worse than being a five-foot-nine, flat-chested freshman, who also happens to be flunking Algebra. Is she ever in for a surprise.

First Mom announces that she's dating Mia's Algebra teacher. Then Dad has to go and reveal that he is the crown prince of Genovia. And guess who still doesn't have a date for the Cultural Diversity Dance?

The Princess Diaries is the first book in the beloved, bestselling series that inspired the feature film starring Anne Hathaway and Julie Andrews.
