England, 1816.
After learning of a conspiracy to kill her estranged lover, a courageous beauty stages an attempt to save his life – no matter how many times she may have wished him dead…

An actress by trade, Julia St. Clement has never played a part so dangerous. With cropped hair, a false mustache, and her friend Sophie posing as her "wife", Julia sets out to warn Lord Anthony Rastmoor of the cruel plot against him.

Despite his betrayal years ago, she still loves him. Rastmoor, however, believes Julia died in another man's bed. His memories of their painful affair have left him wary of everyone. For instance, there's something very odd about this young couple he's just met, especially the husband. The man's face seems so familiar… and too pretty, somehow…

Then shots rip through the night and Julia's "wife" disappears. Rastmoor and Julia are left to form an uneasy alliance. It'll only be a matter of time before he unmasks her – and with a past so passionate, there's no telling what will happen when he does.
