Jane Farnsworth dreams of doing her part in the war against Napoleon, but her reality is limited to the wallflower chairs of London ballrooms. When she makes up an imaginary beau to save herself more torment from her childhood bully, Jane has no idea someone is listening to them. Edward Smith, agent for the Home Office, has a mission: find the genius who broke his majesty’s semaphore codes, and discover if he’s friend or foe. Who’d have guessed that the luscious debutante he overhears mentioning his name, and the code breaker he seeks, are the same? Soon, Edward will have to decide which is dearer to him—his orders, or this newfound love that was never supposed to be real.
