The boy in the striped pajamas

I have recently read the boy in the striped pajamas by John Boyne and wonder what are your views of this book.Bruno is a nine-year-old boy growing up in Berlin during World War II. He lives in a five-storey house with servants, his mother and father and 12-year-old sister, Gretel. His father wears a fancy uniform and they have just been visited by a very important personage called the Fury, a pun which adult readers should have no trouble deciphering. As a consequence of this visit, Bruno's father gets a new uniform, his title changes to Commandment and, to Bruno's chagrin, they find themselves moving to a new home at a place called Out-With. Knowing that it is about the holocaust and very sad and depressing book I am supprised that I read it. I would suggest this book because it was a good read although i prefer not to read sad books. At the end of the book you dont see it coming at all. There is a movie out but it is only showing at certain movie theaters. If you have read the book what did you think of it? And how was the movie if you have seen it?
