He is not, in fact, a member of the Master Race. He has been living a lie to protect his true identity as a Jew — and he’s not alone. Throughout Berlin, Jews survive in secrecy…doing their jobs, caring for their families, maintaining the facade of perfect Aryans, and praying they will not be discovered.But a change is coming. And soon they will be forced to choose between safety and freedom…
