Unsung women and their quest for love, freedom, and second chances. / Caroline Ferriday, a socialite in New York, has her hands full with her post at the French consulate, but on the eve of a fateful war, her world is changed forever when Hitler's army invades Poland in September, 1939; and then sets its sights on France. Kasia Kuzmerick, a Polish teenager, an ocean away from Caroline, senses her carefree youth disappearing as she is drawn deeper into her role as courier for the underground resistance movement. In a tense atmosphere of watchful eyes and suspcting neighbors, one false move can have dire consequences. For Herta Oberheuser, the ambitious young German doctor, an ad for a government medical position seems her ticket out of a desolate life. Once hired, though, Herta finds herself trapped in a male-dominated realm of Nazi secrets and power. The lives of these three women are set on a collision course when the unthinkable happens and Kasia is sent to Ravensbrück, the notorious Nazi concentration camp for women. Their stories cross continents, from New York to Paris, Germany, and Poland, as Caroline and Kasia strive to bring justice to those whom history has forgotten. -- Container.
