The story of this amazing woman was incredibly inspiring. The history of Poland's part in WWII was not something I knew much about and was especially poignant to read in light of the war in Ukraine. Mulley drew the colourful, determined character of Zo in a well-rounded and entertaining way and she highlighted the underestimated and downplayed part that women played in WWII very effectively. Some of the stories were very sad and moving. This book is very detailed and the length and amount of detail may put some readers off. It's a great book and well-researched but be prepared for a deep dive.
