Query: An Excellent book!

Samantha is an outcast, and doesn't care. Her sister Lucy is the most popular girl in school, with a cute boyfriend, Jack, who Samantha likes. Her younger sister is a geinus. Suddenly her sister reports to her parents that shes been drawing her friends with celeberties, and they make her take art lessons. She saves the president outside of one, and everything changes for Sam.I recommend this to people who enjoyed the Princess Diarys. Just be aware that the book contains a little bit of inappropriate lanugage. I read this in 6th grade, and have read it several times since. I think this book is definitly worth buying!
