In 1814 England, Stranje House, a School for Unusual Girls, appears to be a place that reforms unmanageable girls into proper young ladies. However, Headmistress Emma Stranje instead trains the young women in espionage, diplomacy, and war. When Miss Georgiana Fitzwilliam is first sent to Stranje House, she plans to escape, but then she meets Lord Sebastian Wyatt and the two embark on a quest to invent invisible ink for the English war effort.
