like and dislike about my book

The book I am reading now is Prisoner B-3087. Its about a boy named Yanek Gruener, who talks about all the concentration camps that he went to and all the bad things the Nazis have done. The one thing I like about the book is that it describes the settings really good. It makes it feel like I am there. The only thing I really don't like about the book is it tells you how Jews are killed on the streets, beaten, and even eaten by dogs. But other than that I really enjoy this book.
