London 1794

Tess Murray, once a maid in a fashionable London townhouse, traded her apron for a pair of breeches to become a spy--a decision that cost her the man she loved. Determined to become a spymaster and command her own team, Tess is hunting a traitor smuggling muskets to France.

Sebastian Moore, Duke of Northfield, spent ten years fighting to save his family's reputation. When he finds Tess in his warehouse--and muskets hidden among the goods ready to be shipped--he realizes everything he has worked for is at stake.

He might be a suspect, and she might be a spy, but passion has no rules.
