This powerful memoir traces Brazilian-born American Julie Lindahl's journey to uncover her grandparents' role in the Third Reich, as she is driven to understand how and why they became members of Hitler's elite, the SS. Out of the unbearable heart of the story - the unclaimed guilt that devours a family through the generations - emerges an unflinching will to learn the truth.

In a remarkable six-year journey through Germany, Poland, Paraguay, and Brazil, Julie uncovers, among many other discoveries, that her grandfather had been a fanatic member of the SS since 1934. During World War II, he was responsible for enslavement and torture and complicit in murder of the local population on the large estates that he oversaw in occupied Poland, before fleeing to South America to evade a new wave of war-crimes trials.

The pendulum used by Julie's grandmother to divine good from bad and true from false becomes a symbol for the elusiveness of truth and morality, but also for the false securities we cling to when we become unmoored from them. As Julie delves deeper into the abyss of her family's secret, discovering history anew, one precarious step at a time, the compassion of strangers is a growing force that transforms her world and the way that she sees her family - and herself.
