This is a great book! It's about Mia Thermopolis, a normal, American, 14-year-old girl, who's main worry in life is the fact no one's ever asked her out and her mum is dating her algebra teacher. That is, until her dad tells her she's actually the Princess of Genovia! This causes lots of problems - she has to have a bodyguard with her, she loses her best friend, and she has to take "princess lessons" with her grandmother, who she loathes! The book is written in the form of Mia's journal, which also includes lists of things to do and algebra notes. This is a great book and I can't wait to get the sequel!
