Personal Review: I have been reading the Princess Diaries series since I was twelve years old and they never get old to me. Mia is one of those characters that will always entertain you. She is always getting herself into some kind of problem. In this book watching her go through a depression is sad, but at the same time very funny. If you have read the other Princess Diaries books, you are sure to like this one.
