I read this book when I was in high school, but I didn't read it for school. Although, it is frequently used as a book for high school literature classes.
I've read this book only a couple of times because it is a very emotionally charged book, but I have purchased it at least a half dozen times because I keep giving it to people.
This book changed me. It changed the way I see the world and it opened my eyes to things I never was aware of before reading it.
