A biography of the Warsaw Zoo and it's caretakers during WWII. I found it interesting, but I became lost several time and found myself skimming the words. The book did not include a pronunciation guide for the names and words and it was really full of technical and scientific language. Several chapters would also be on different people or happenings than just the Zoo and the activities that occurred there. The book ended up being more an overall book about WWII in Warsaw and the resistance there than about a zoo and the family that hid people. The unnecessary facts (that felt forced into the story) detracted from the Zabinskis', the war and the effect on them and the zoo.
