The Sonderkommando, who were work units of Nazi death camp prisoners forced to aid the killing process at Auschwitz and Birkenau camps, consisted mainly of Jewish prisoners. The book is based on interviews with survivors of units of the Sonderkommandos. A note by the publishers states: "The book provides direct testimony about the "Final Solution of the Jewish Problem," but it is also a unique document on the boundless cruelty and deceit practiced by the Germans. It documents the helplessness and powerlessness of the one-and-a-half million people, 90 percent of them Jews, who were brutally murdered in the gas chambers of Auschwitz-Birkenau."^[3]
