BERLIN, 1942. The Gestapo arrest eighteen-year-old Bert Lewyn and his parents, sending the latter to their deaths and Bert to work in a factory making guns for the Nazi war effort. Miraculously tipped off the morning the Gestapo round up all the Jews who work in the factories, Bert goes underground. He finds shelter sometimes with compassionate civilians, sometimes with people who find his skills useful and sometimes in the cellars of bombed-out buildings. Without proper identity papers, he survives as a hunted Jew in the flames and terror of Nazi Berlin in part by successfully mimicking non-Jews, even masquerading as an SS officer. But the Gestapo are hot on his trail…

Before World War II, 160,000 Jews lived in Berlin. By 1945, only 3,000 remained alive. Bert was one of the few, and his thrilling memoir—from witnessing the famous 1933 book burning to the aftermath of the war in a displaced persons camp—offers an unparalleled depiction of the life of a runaway Jew caught in the heart of the Nazi empire.

"On the Run in Nazi Berlin should be mandatory reading: a memoir that reads like a thriller, full of suspense, horror, humor, and the unquenchable determination to survive. An important contribution to the literature that reminds us: never forget." — Jenna Blum, Bestselling author of Those Who Save Us and The Lost Family

"[Offers] extraordinary insight... Well-written, readable, and honest, the eyewitness story is enhanced throughout by photographs and documents. This story of this Jewish family touched my heart, and I highly recommend this memoir."— Denise George, Coauthor of The Lost Eleven and Behind Nazi Lines

"a grim and gripping story of survival in a most egregious time." --Kirkus Reviews
