France, 1942: While war blazes at the front lines of Europe, in the walled southern city of Carcassonne, nestled deep in the Pyrenees, a group of courageous women is engaged in an equally lethal battle. Like their ancestors who fought northern invaders 700 years before, these members of the French Resistance - code-named Citadel - fight to liberate their home from the Nazis. Led by a daring 18-year-old, Sandrine Vidal, and her elder sister, Marianne, the women of Citadel work quickly to sabotage their German occupiers, safeguard their neighbors and smuggle refugees over the mountains into neutral territory.

Set during World War II in the far south of France, Citadel is a powerful, action-packed mystery that reveals the secrets of the resistance under Nazi occupation. While war blazed in the trenches at the front, back at home a different battle is waged, full of clandestine bravery, treachery and secrets.
