One woman faces danger, intrigue, and love in the aftermath of World War II in this unforgettable novel from the New York Times bestselling author of The Lost Girls of Paris.

1945 . Marta Nederman has barely survived the brutality of a Nazi concentration camp, where she was imprisoned for her work with the Polish resistance. Lucky to have escaped with her life, she meets Paul, an American soldier, who gives her hope of a happier future. The two make a promise to meet in London, but Paul is in a deadly plane crash and never arrives.

Finding herself pregnant and alone in a strange city, Marta finds comfort with a kind British diplomat, and the two soon marry. But Marta’s happiness is threatened when the British government seeks her help to find a Communist spy—an undercover mission that resurrects the past with far-reaching consequences.
