Inspired by true events, this is the story of how society's 'lovely ladies' won a war. Each year at secluded Shillings Hall, in the snow-crisped English countryside, the mysterious Miss Lily draws around her young women selected from Europe's royal and most influential families. Her girls are taught how to captivate a man—and find a potential husband—for in 1914, persuading and charming men is the only true power a woman has. Sophie Higgs is the daughter of Australia's king of corned beef and the only 'colonial' brought to Shillings Hall. Of all Miss Lily's lovely ladies, however, she is also the only one who suspects Miss Lily's true purpose. As the chaos of war spreads, women across Europe shrug off etiquette and become the unacknowledged backbone of the war, creating hospitals, canteens and transport systems where bungling officials fail to cope. And when tens of thousands can die in a single day's battle, Sophie must use the skills Miss Lily taught her to prevent war's most devastating weapon yet. But is Miss Lily heroine or traitor? And who, exactly, is she?
