Becoming a spy for the resistance after the Nazi's invade Poland, Emma Bau, taking on a new identity as a gentile, becomes a high-ranking Nazi official's assistant and, leading a double life, compromises her marriage vows, her safety, and the lives of those she loves for the cause.

1945. Surviving the brutality of a Nazi prison camp, Marta Nederman is lucky to have escaped with her life. She meets Paul, an American soldier who gives her hope of a happier future. But their plans to meet in London are dashed when Paul's plane crashes. Devastated and pregnant, Marta marries Simon, a caring British diplomat, and glimpses the joy that home and family can bring. Her happiness is threatened when she learns of a Communist spy in British intelligence-- and the one person who can expose the traitor is connected to her past.-- adapted from jacket
