Query: Harrowing writing, perhaps

You wouldn't have thought it was possible for a book about such a serious, important subject, to be so bland, but I am afraid the most harrowing thing about reading this is the dull prose of this book, written as if by a school student for a teacher they wanted to impress. There are many better books about the nightmare of Dachau. Don't waste your time on this badly written piece of literature.
