Query: Horrible Book!

This is one of the worst books I've ever seen. It is very depressing. It does not show an accurate description of the last 100 years. It shows all the war and killing and negative side of everything. I do not recommend this book to anyone. The pictures are gross!! Please do not show this book to children unless you want them to think everything is terrible. I usually love books like this but was very upset by this book.
