A novel by Constance Ravenlock
Rita Awards Best Novel
They had saved her life knowing she could be a spy. That alone was enough to put Alexis Palme forever in debt to the eccentric Count and Countess de Chambord and the dark, brooding Dr. Edouard Lautrec. But now the shipwrecked beauty was up to her lovely neck in their dangerous game of smuggling and treason, courting the guillotine in Napoleon's France and playing the beautiful-but-dumb decoy to the vainglorious enemy, colonel Barouche, who vowed to have her--or see her dead. Alexis was left with only her wits, her charm, and the reluctant help of Edouard, the only man who refused to be her pawn.
