I'm not a very emotional person, but the one book that made me cry for 3 days straight ( know, long time) is "A Child Called It" by Dave Pelzer.
It's his lifestory, and my gosh it made me cry and cry and CRY! It's about a little boy (Dave) who was put through one of the most severe cases of child abuse in American history, by his own mother.
I recommend this book to one and all, because it's opened my eyes, and I'm sure it'll open yours, =)
