A Violent Book About Anti-Violence... . While this book has good intentions, I found it to be the most violent book about anti-violence that I could imagine. The text is not so bad, but the illustrations gave me chills. I thought it couldn't get any worse (guns, knives, etc.), when I came to a page where a little boy was lying in a pool of blood hugging a teddy bear. In my opinion, this is not the kind of book that should be viewed by any child, let alone a child who needs a book about anti-violence
Output:
NEG
