This is one of the worst books ever written. This book teaches girls that just because you're boyfriend dumps you it's okay to engage in self-destructive behavior. Bella is the worst role model any girl could ever find, she's a boring, self-pitying, moron who can't function without her angsty, emotionally abusive, stalker boyfriend.
This book is appropriate for ten year-old's, but I don't think they should ever read it. It will turn them into obbsevive little fangirls, who need to go get a life.
If you want to read this book, go buy a copy, burn it, and go read a real book. If you're strapped for cash, cut out the middle part and just to read a real book.
Here are several suggestions:
Flowers for Algernon by Daniel Keyes
Call of the Wild by Jack London
Watership Down, by Richards Adams
All Creatures Great and Small by James Herriot
SO if you ever have the urge to read New Moon, or any other book in the Twilight 'Saga', just look at the list of books above, They're all awesome, plus they're well written and have a plot, two things all of Stephanie Meyer's books lack.
