In the shadow of the First World War, where loyalties fracture and love becomes a weapon, Josette is reborn from loss. Once a young German woman with a quiet life and a future filled with promise, she loses everything in the chaos of war-her family slaughtered, her lover taken from her in an act of ruthless betrayal. Grief hardens into resolve, and vengeance becomes her only remaining purpose. Recruited and trained in the art of deception, Josette is reshaped into a weapon: taught how to read men, manipulate desire, and survive in a world where a single misstep means death. Given a new identity, she is sent behind enemy lines to France, where she must erase her past and weave herself into high society, posing as a noblewoman of impeccable manners and irresistible charm.
