Query: Required reading for humans

I read "Man is Wolf to Man" three years ago, and it haunts me to this day. I had read many accounts of WWII Europe, the Holocaust, and the Gulag, but none so acutely personal and sensitively written as Bardach's. Currently I'm reading "When God Looked the Other Way" by Wesley Adamczyk, a narrative of Polish deportees to the Soviet Union told from a similarly youthful perspective. Historians, soldiers, politicians, and students should place these books at the top of their reading list.
