Masterfully constructed, this book knows how to make moving, poignant and a multitude of exciting stories. In a few lines the author we are interested in the fate of each contributory family, by putting it in perspective with historical themes. A book really "Participatory", making a collective tribute to the suffering and hairy their families that they come out of anonymity by giving names and citing specific individuals. Always with great respect for these men and women who have suffered so much.
