  "description": "A riveting spy novel and major work of literature, Waltenberg is the compelling tale of Michael Lilstein, an East German spymaster and Auschwitz survivor who recruits a mysterious young Frenchman to act as a mole, much to the interest of the CIA. Intertwined with this history is the relationship between a German novelist and an American singer, and the friendship between the novelist and a French journalist- but at its heart Waltenberg is an espionage novel and betrayal lies at its core.",
