Jem Riseley is the perfect soldier in Wellington's army—brave and skilled, but also a lady! A battlefield promotion provides Jem with the means of escape from a sadistic major, but leaves her with the problem of Captain Tony Dorrell. Jem must convince the handsome but jaded captain, who knew her as a lady, that she's the man she seems. When the pair are trapped behind French lines, Jem has to battle the enemy as well as her rekindled desire for Tony. From the dangers of war-torn Spain to scandal in London's elegant drawing rooms, Jem will fight to preserve her secret. However, the reappearance of an old adversary causes Jem to confront her past in order to save her own, and England's, future.
