I quite enjoyed this book. Meg was a really mature 12-year-old, and while this book was short, she sure did learn a lot. She also had a lot to deal with, with her father leaving, and her best friend Gracie pretty much being a butthole throughout the entire story.
Meg did even come clean as far as the dreams at the very end of the book, and the fact that she made a new friend that was a much better person than her current best friend made the book worth reading. :)
