I'm not sure why, but I got bored with this book about a third of the way through. I loved it in the beginning, finding the internal life of the main character so real and compelling and lovable. And the way she dealt with her burgeoning feelings toward her friend was funny and so well written. But as the book moved on I found the writing less interesting. Not as psychologically astute, I guess, it started to feel more generic.
But reading other peoples' reviews makes me think I missed the boat and should go back and read it again!
