the book reads quickly grabs you and does not release you. Important book for understanding the horror at its fair measure. The reader is not spared, he must face a terrible reality. You have to be a superman to be able to live after being a Sonderkommando, that's my feeling. But it is important to know everything, learn all about the death camps and we must say that the lives of sonderkommandos is not often brought to our attention. We do not talk about or it is mentioned without linger like this these men had not really existed or as it it was not necessary to talk about. This book is very important, it should be read as other testimonies about life and death in the camps.
