When France falls to Germany in 1940, wealthy socialite Violet St. Croix could honor her parent's wishes and ride out the war on the French Riviera in comfort with lavish parties and couture gowns. Instead she defies the expectations of her time and travels to London to join General de Gaulle's Free French forces. Despite doubts because she's never worked a day in her life, Violet uses her love of driving fast cars to her advantage and eventually proves her worth. With her reputation for nerves of steel and her extraordinary aptitude for navigating dangerous conditions, she earns an assignment driving senior officers for the French Foreign Legion. As the war escalates, Violet finds herself in North Africa as the Allies try desperately to defend the advances of Rommel's Nazi forces. All women are ordered to leave the front but Violet insists on staying and won't abandon the fight. After a series of failures, Violet begins to suspect that there is a traitor in their midst, sabotaging their efforts by providing intel to the enemy. Then her supervising officer dies, and she is certain that it is not an accident but murder, although convincing her colleagues proves nearly impossible. So together with the one man who believes in her and her theory, she must identify the spy. Determining who else to trust in order to survive might just be her most dangerous assignment of all. Based on the true life story of Susan Travers -- the only woman to ever serve in the French Foreign Legion -- this novel celebrates a daring woman who used her courage and strength of will to not only save lives but save her country.
