Oh man, I have a love/hate relationship with WWII novels, and try to read no more than one a year. Or in some cases, like after reading Sarah's Key, I needed a few years to recover. Having read All the Light We Cannot See back in January, I was able to squeak this one in before the end of the year. I'm having a hard time deciding if I like one better than the other (they were both outstanding) - and if one, or both, should be on my favorites for the year. This story of French sisters Vianne and Isabelle is heartbreaking, obviously in terms of their struggles during the war, but also in terms of their struggles as sisters. At the heart of the novel is a beautiful story about family, and what we do for love. Another book worthy of the hype.
