From the Notebooks of a Middle School Princess

Olivia has always considered herself average:  average smart, average height, even her skin is an average brown.  The only things about her that aren't average are her ability to draw, and the fact that she's basically an orphan.  Her mother died when she was a baby, and she's never really met her father.  She's talked to him on the phone, and she writes letters all the time, but his job makes it difficult for them to meet in person.

But Olivia is not average, and the truth comes out when the school bully starts taunting her one day about being a princess.  Olivia knows it isn't true and tries to fight back, but maybe she's wrong.  The truth comes out when none other than Mia Thermopolis shows up at Olivia's middle school and explains that Olivia is actually her half sister!

This explains a lot.  Her mother wanted her to have a normal life, so her father, the crown prince of Genovia, had to keep his distance, and her aunt and uncle raised her alongside her horrible cousins.  But all her worries could be over because Olivia really is destined for an extraordinary life!

This is the first book in a new series by Meg Cabot, and all your favorite characters from The Princess Diaries are here in supporting roles.  My only complaint is this book is pretty much all set up.  I guess we have to wait for book two for Olivia's adventures to begin.
