1944. Physics professor Alfred Mendl is separated from his family and sent to the men’s camp, where all of his belongings are tossed on a roaring fire. His books, his papers, his life’s work. The Nazis have no idea what they have just destroyed. And without that physical record, Alfred is one of only two people in the world with his particular knowledge. Knowledge that could start a war, or end it.

Nathan Blum works behind a desk at an intelligence office in Washington, DC, but he longs to contribute to the war effort in a more meaningful way, and he has a particular skill set the U.S. suddenly needs. Nathan is fluent in German and Polish, he is Semitic looking, and he proved his scrappiness at a young age when he escaped from the Polish ghetto. Now, the government wants him to take on the most dangerous assignment of his life: Nathan must sneak into Auschwitz, on a mission to find and escape with one man.

The One Man, a historical thriller from New York Times bestseller Andrew Gross, is a deeply affecting, unputdownable series of twists and turns through a landscape at times horrifyingly familiar but still completely compelling.
