When time stopped: a memoir of my father's war and what remains

In 1941, the first Neumann family member was taken by the Nazis.
Of thirty-four Neumann family members, twenty-five were murdered by the Nazis. One of the survivors was Hans Neumann, who, to escape the German death net, travelled to Berlin and hid in plain sight under the Gestapo’s eyes. What Hans experienced was so unspeakable that, when he built an industrial empire in Venezuela, he couldn’t bring himself to talk about it. All his daughter Ariana knew was that something terrible had happened.
When Hans died, he left Ariana a small box filled with letters, diary entries, and other memorabilia. Ten years later Ariana finally summoned the courage to have the letters translated, and she began reading. What she discovered launched her on a worldwide search that would deliver indelible portraits of a family loving, finding meaning, and trying to survive amid the worst that can be imagined.
