If you ever want to read about the psychology behind the prisoners in the Concentration Camps during the Holocaust, this is the book to read. It is written by a psychotherapist who was a survivor and he uses his own stories to break down why people act the way they do in such depraved situations and why people were able to live and have hope after all this was done to them.

Great for people who want to study psychology, or for people like me who are just interested in it.

It is a very powerful book.
