Based on the true story of Jack Gruener, Prisoner B-3087 gives readers a look at 10 different concentration camps in Nazi-occupied Europe. The story takes readers from before the Germans invaded Poland, to after the Americans liberated Dachau. In the author’s note, Gratz says he took liberties with the story, with the permission of Gruener, so that readers could see the atrocities enacted on people who didn’t fit into Hitler’s Aryan ideal.
It’s always nuts, reading about the Holocaust. It’s hard for me to fathom, given my lived experiences, people treating other humans worse than animals (to the point where members of the SS are punished for torturing animals but encouraged to torture humans).
