A wonderfully written book about the German invasion of Poland and the destruction of life-human and animal. Despite the horrific atrocities the Germans commit upon the citizens of Poland, Jewish and Christian alike, the author tells a story of hope. The zookeeper of the Warsaw zoo and his wife are able to maintain their villa and use it as a temporary home for Jewish citizens trying to escape the Nazis. The zookeeper is also a major player in the Underground movement and the zoo grounds become a hiding place for explosives, etc. There is Polish history interwoven throughout the book as well as discussion of wildlife and natural places. I am of Polish descent and this book has created a yearning in me to learn more of my heritage and the bravery of Poland's citizens. An engaging book--I highly recommend this!
