From the riveting testimonies and files housed at Yad Vashem, Holocaust historian Mordecai Paldiel presents dozens of stories of the circumstances and odds facing Jews inside Nazi-dominated Europe and those who would help them. Highlighting the aid and assistance of non-Jews, Paldeil demonstrates that the awesome efficiency of the Nazi death machine did not rule out heroism by ordinary people, in spite of risks. Stories and photos focused on conditions of sheltering, movement of people across borders, passing as a gentile, rescues of children, an dangers of detection epitomize the radical altruism, courage, and ingenuity that helped some Jews to survive the darkest moment in history.
