An extraordinary memoir by a survivor of the Nazi camps, Yves Beon, Planet Dora is a recollection of life and death in a concentration camp like no other. Dora was a cavernous underground factory cut out of solid rock, where life was like a nightmarish scene from Dante: thousands of prisoners beaten, starved, killed, and living underground for weeks at a time. The purpose of all this brutality was to build the world's first operational rockets: the V-1 and V-2 missiles, Hitler's vengeance weapons.
