Not set up as a typical fiction novel, this true story is pieced together like narrative non-fiction with imagined dialogues and thoughts. Even with that caveat it was still a wonderful story. A little disjointed in places, but overall the flow is great and the many pieces of this giant jigsaw come together with Ackerman's skilled writing. She tells the story of the Polish zookeepers who fight not only for their beloved animals but for those suffering around them in Nazi occupied Warsaw. Over the years they help shelter and feed hundreds of Jews and even allow some of them to reside in their house with their family. It's a touching story and I hope that they do the movie version justice.
