Auschwitz: A Short History by Ben Stevens is a documentary style story. I gave it four stars because it was a straightforward account of history.
It is sad to remember the atrocities that took place. There were the "Einsatzgruppen - paramilitary 'death squads' who followed the regular German army into occupied territory before 'cleansing' it of anyone deemed racially or politically 'undesirable'. Previously, this had consisted chiefly of Einsatzgruppen soldier shooting unarmed men, women and children in the back of the head, or machine-gunning them in large groups, before hurling their bodies into deep trenches." There were 33,771 people killed in a massacre in Kiev in September 1941.
I received a complimentary Kindle copy in an Amazon promotion. That did not change my opinion for this review.
