Lady Elizabeth Neville-Ashford wants to travel the world, pursue a career, and marry for love. But in 1914, the restrictions of British society and her mother's expectations forbid Lilly from following her heart. When war breaks out, she seizes her chance for independence. Defying her parents, Lilly moves to London and becomes an ambulance driver in the Women's Army Auxiliary Corps--a treacherous job that takes her to the Western Front. Assigned to a field hospital, Lilly is reunited with Robert Fraser, her brother's best friend. She doesn't care that the hand-some Scottish surgeon grew up in poverty--she yearns for their friendship to become something more. Lilly is the most beautiful--and forbidden--woman Robbie has ever known. Fearful for her life, he's determined to keep her safe, even if it means breaking her heart. In a world divided and filled with uncertainty, can their hope for love survive . . . or will it become another casualty of war?
