Books in the The Charlotte's War Trilogy series

Freya Jorgensen is not her real name. Charlotte de Tournet had to hide her true identity when the Nazis rolled into Paris. The SS took over her Avenue Foch mansion, Le Palais, for use by high-ranking Nazis as a place to relax away from the war. She is young and beautiful and is held virtually captive in her Paris mansion. Her only trusted friend is Theodora, a Turkish prostitute and courtesan at Le Palais. Freya unwisely falls in love with a handsome SS officer, Jost Krupp. As Freya discovers her lover is a mass and indiscriminate killer, she and Theodora escape Le Palais before her identity is discovered and the mansion is blown up. With the help of Baron Ferdi Saumures, they flee Paris and travel to southwest France and meet British SOE agent, Bertrand. Freya's adventures are just beginning.
