Memoirs of a Teenage Amnesiac

As the book went on, I cared less and less for Naomi. She didn't seem 17, but much younger and less mature - but then, even when I was 17, I can't stand most girls that age. She used her amnesia for very selfish reasons and never seemed to want to know much about her past, not because she was scared, but because it would get in the way of her selfish goals she set for herself after her accident. She used it to manipulate people that seemed only to be trying to help her. How she treated Will and her parents was disgusting. I can only assume she had this personality type - both before and after the accident - because she was given so much freedom as a child. How she was towards her mother, adoptive or not, and how her mother just let it go was so mind-blowingly unrealistic I couldn't believe it.
The main reason I finished this book is that Zevin is an excellent wordsmith and I did want to know how the story ended, even if I had stopped caring about Naomi long before I reached the half-way point. I would have much rather read a story about James' past or Will in general - they were much more interesting, though also not entirely believable, characters.
