Defy the Darkness
A Tale of Courage in the Shadow of Mengele
This is the story of a young man caught in the whirlwind of the Holocaust, who survives a chain of events so harrowing they almost defy belief. As a boy, Joe Rosenblum watches as the Nazi overlords tighten their grip on his small Polish town. Narrowly escaping mass executions that take his own brother, Rosenblum is first sheltered by a local Gentile family, then takes refuge with Russian partisans. Once captured by the Germans, he begins a journey through three concentration camps--Majdanek, Auschwitz, and Dachau. Living by his wits, a courier for the camp underground, Rosenblum is able to help other prisoners, and even to save children selected for the gas chambers. Eventually he finds himself working for the infamous Dr. Mengele. In a bizarre twist of fate, the Angel of Death is persuaded to perform life-saving surgery on Rosenblum--perhaps making him the only Jew to be saved by the deadly doctor's skills. A remarkable man who danced on the razor's edge of history, Rosenblum did not merely survive the Holocaust, but rose above it by radiating hope and humanity--by defying the darkness.
Beyond its central premise, the book can be read through the connected lenses of Nonfiction. Those themes offer useful points of attention as the characters, ideas, or world develop, especially where the book complicates the expectations of its primary category.

Read for connection, not completion.

Three questions to carry with you
- Whose perspective organizes the story, and whose perspective remains outside it?
- Which sources or lived experiences carry the author’s central argument?
- How does the book change the way you understand its larger subject?
