The Zookeeper's Wife. Diane Ackerman.
If Hitler had a hierarchy of hate, Poles were somewhat better off than Jews, but not by many rungs. Ackerman's book is a truly fresh perspective on the Holocaust, from inside Warsaw (85 percent destroyed in WWII) and from the viewpoint of Antonina Zabinski, wife of Jan, keeper of the Warsaw Zoo. Animal life took a beating along with everything else in the war -- the zoo was bombed during the 1939 invasion. In a beautiful twist, the mostly empty zoo became a place of shelter for 300 Polish Jews during the war years. The Holocaust and WWII are so overwhelmingly evil and destructive that I am compelled to understand the resistance to Nazis. It is documented at Auschwitz, and documented here; at the Zabinski home, Jews lived in hiding alongside Jan (who worked with armed Resistance forces), Antonina, their little boy Rys, a chicken, a hamster, a badger, a muskrat, a rabbit (those were among the various house pets.) A wide circle of species, interconnected, learning survival.
