In 1941, the first Neumann family member was taken by the Nazis, arrested in German-occupied Czechoslovakia for bathing in a stretch of river forbidden to Jews. He was transported to Auschwitz. Eighteen days later his prisoner number was entered into the morgue book.

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, traveled 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.

A "beautifully told story of personal discovery" (John le Carré), When Time Stopped is an unputdownable detective story and an epic family memoir, spanning nearly ninety years and crossing oceans. Neumann brings each relative to vivid life, and this "gripping, expertly researched narrative will inspire those looking to uncover their own family histories" (Publishers Weekly).
