Author's Note: I am explaining why I think Meg Cabot wrote the book Party Princess.
Meg Cabot wrote Party Princess to describe what high school is like. In this book she describes what Mia is going through in high school. Meg Cabot tries to put a picture into the reader's mind about what high school is actually like.
For example she explained what a high school play is like. They talked about how sometimes people are really really good and don't get the part and how some people are really bad and they do get the part. In the book Mia was really bad at did get the part and Lilly; Mia's best friend, was really good and didn't get the part. Also she wrote about how Mia didn't like some of the people she was working with but had to work with them anyways.
So now you know what a play is like in high school. Bit another good example is family. Meg Cabot talked about how Mia's grandmother was trying to help them raise money for the school and she decided to write a whole musical for her. So the point is that even though family members can go overboard sometimes they still love you.
Family can go a little overboard sometimes.But so can friends. Meg Cabot also talked about how Lilly decided to write a whole magazine just about Mia's cat to try and make Mia feel better. She went a little bit overboard. But she did make Mia feel better.
