Juliana Telford is not your average nineteenth-century young lady. She's much more interested in researching ladybugs than marriage, fashionable dresses, or dances. So when her father sends her to London for a season, she's determined not to form any attachments. Instead, she plans to secretly publish their research.
Spencer Northam is not the average young gentleman of leisure he appears. He is actually a spy for the War Office, and is more focused on acing his first mission than meeting eligible ladies. Fortunately, Juliana feels the same, and they agree to pretend to fall for each other. Spencer can finally focus, until he is tasked with observing Juliana's traveling companions . . . and Juliana herself.
