This book, easily accessible (and therefore advise to high school students and even college students interested in the period), is a moving testimony to the reality of the concentration camps, too often obscured or softened. Here, however, no voyeurism, no violence or gore but a very worthy description, very posed, and the life Lager. It is not in the sensational, on the contrary, the tone is very quiet, very realistic, and imbued with a sensitivity that does not leave indifferent. A vision of the interior, with the meditations of an inhabitant of the camp, his daily struggles to survive, and its conclusions (notably in Appendix) this shocking episode of his life. Rewarding, interesting, vital not to forget.
