It doesn't hurt to read the book.
I think it might give you a more detailed back ground of everyone.
It's a very emotional book and the movie looks so as well, as it should be.
It's a very extraordinary story through Susie's eyes. The book is so well written and such a sad story. I'm definitely glad they made it into a movie. When I was reading the book, I imagined it as a movie. It's such a heart felt story, and the sad thing is, things like that happen in real life, and it's such a different perspective when you see the story told from the eyes of the deceased victim.
