Book excerpt: Through the author's restrained, precise style, combining personal memories and the researcher's scholarly detachment, the reader discovers the many facets of the camp: the hierarchical structure of the camp established and controlled by the SS, the categories of prisoners, their daily life, the arbitrary and escalating violence, the selections, the medical experiments and the role of the SS physicians, the intentional and programmed extermination, the camp's evacuation, the typhus epidemic, and liberation.
