3.5/5 - Full review at emileereads: http://emileereads.com/blog/2017/3/14... 
 Overall, The Nightingale was a thought provoking book even if I did wish for more depth in parts. It was a 3.5 out of 5 for me and I would happily try some of Hannah's other novels in the future. 
 The sisters and their relationship were the highlight of the novel. Isabelle was immature at first, but as she aged she grew up and I came to love her. She was brave, determined, and a hero. (view spoiler)[(By the end, it seemed like every character - not just Isabelle - was undercover against the Nazis, which is nice to imagine, but not factual or realistic. Readers more knowledgeable on the time period than me have pointed out plenty of the historical inaccuracies on Goodreads.) (hide spoiler)]Vianne, throughout most of the story, was understandably focused on her daughter and keeping her safe. She believed she couldn't risk her family for Isabelle's ideals, and their alternating convictions kept them at odds in spite of a clear love for each other. 
 Isabelle, the secret hero, was the more interesting sister. (view spoiler)[I was disappointed with how little we saw of Isabelle's treks across the mountain range. The first time she made the journey with the downed pilots was my favorite part of the book. (hide spoiler)]She was so determined to do something! All her life she'd been forced to sit and be ladylike, and she finally was able to fight. It was a huge triumph of hers, and the most dramatic action of the novel, and yet it was such a short section. Instead, there were way too many explanations of the various days standing in line for food. 
 This book was very realistic when it came to the women's emotions and relationships. Vianne and Isabelle fought like all sisters do but loved each other deeply, even from a distance. The modern day chapters brought the story full circle and showed the power of a fighter's convictions, decades later. This was a worthwhile book because of the women, and I would recommend it to fiction readers for that reason.
