The story of the Zookeeper and his wife is very interesting in and of itself. Unfortunately, the book is full of sometimes off topic meandering branches of details that stray away from the focus of the story. Additionally, there's a bit of name dropping -- Irene Sendler and Janusz Korczak, as if the author was trying to fill pages and connect more directly to wider Holocaust narrative. Since the subject of the story is fascinating in and of herself, it would have been better to just focus on their story.
