A Jewish member of the French Resistance, Sim Kessel lived for almost three years in Nazi captivity. The bulk of his time was at the Auschwitz concentration camp, where he survived torture, starvation, and even his own public execution through extraordinary luck. His remarkable and terrifying story shows in knowing and intimate detail how guards and kapos under the Nazi system degenerated into conscienceless killers, and how the desperate scramble to survive dehumanized Kessel's fellow prisoners.
