A beautiful/horrific story of two sisters throughout World War II in France. The novel is beautifully written, a little too detailed at times which I felt made it drag a bit, but gorgeous prose such that I was so engrossed in the story that I kept having to put it down for a day or two because it was stressing me out. Some of the history of course I know but some, like how women were such a part of the resistance, I did not. Graphic details of abuse and concentration camps were incredibly hard to read but overall it is a novel of strength and family and extreme persistence in the face of unspeakable evils. I found myself crying, shaking my head in disbelief, and rooting for the characters to keep fighting and "stay alive."
