Kristin Hannah delivers an absolutely gut-wrenching story of two French sisters during WWII. If you’ve ever had a complicated sisterly relationship, parts of this book will hit you like a punch to the stomach. In school, we studied different perspectives of WWII, but I realized as I read this book that I had never really explored the war from the French resistance’s point of view. And while the characters themselves are fictional, the themes of loss, sacrifice, and survival are very, very real—and you feel that in Hannah’s writing.
