Hitler's air force was banned by treaty. Germany built it anyway — in secret, on Russian soil.

Berlin, 1926. Captain Tom Munro flies passenger routes for a German airline — and quietly reports what he sees to British intelligence. Deep in the forests of Soviet Russia, German engineers are testing the warplanes the Treaty of Versailles swore would never exist. Munro means to prove it.

But the only way to expose the secret base at Lipetsk is to get inside it. There, he flies as a test pilot for men who would shoot him as a spy — and the only way out is to fly through everything they send after him.

He went looking for the truth about the next war. Now he has to live long enough to bring it home.
