Deceiving the Duke

In 1806, Philomena St. Gobain disguises herself as a man to attend science meetings and sell her inventions, keeping her true identity secret from the handsome Duke of Tenwick. When the duke unexpectedly confronts her and later appears at her ball with a vital invention, their worlds collide in ways neither expected. As the duke investigates a spy passing secrets to France, he begins to suspect that the woman he's falling for might be more deeply involved than she appears.
