Book

The Black Swan of Paris / Karen Robards.

Summary:

"A world at war. A beautiful young star. A mission no one expected. Paris, 1944. Celebrated singer Genevieve Dumont is both a star and a smokescreen. An unwilling darling of the Nazis, the chanteuse's position of privilege allows her to go undetected as an ally to the resistance. When her estranged mother, Lillian de Rocheford, is captured by Nazis, Genevieve knows it won't be long before the Gestapo succeeds in torturing information out of Lillian that will derail the upcoming allied invasion. The resistance movement is tasked with silencing her by any means necessary--including assassination. But Genevieve refuses to let her mother become yet one more victim of the war. Reuniting with her long-lost sister, she must find a way to navigate the perilous cross-currents of Occupied France undetected--and in time to save Lillian's life."-- Publisher's description.
