** spoiler alert ** 
 (SPOILERS AHEAD) I adore this book so much. This is now the second time I've read it and it still makes me cry! I'm very attached this book because of my background in genocidal studies/history and the fact that it intrigues me that de Rosnay draws you in with both stories. The first time I read it, I kind of hated the switching back and forth of the chapters but the second time it didn't phase me. I know why de Rosnay did it and it works so well for this book. The optimist in me, kind of wishes (still after the second reading) that Julia would have found Sarah alive in the end, but I get why de Rosnay played it out the way she did.
