This book is thorough, graphic, tense, heartbreaking, and stunning. It is a tremendous book. It is certainly one of the best I've ever read on the Holocaust. This book is written by a man who literally worked in the gas chambers. If anyone knows the truth, it is this man. His story will stick with you long after you finish reading the book. The fact that people today are still trying to persecute Jewish people is disgusting beyond words. They need to read this book, too.
