As the most enviable comtesse of the tonne, Charlotte de Brionne was almost satisfied with her wealth, power, and rather tepid marriage, until her murderous husband betrayed her. Now she has seized the chance to make a more adventurous start with les Dames Dangereuses, an order of women spies in service to the French crown. But her latest assignment is rudely interrupted when she is kidnapped by a crossbow-wielding madman, who turns out to be not at all mad only rather surly and annoyingly handsome. Lieutenant Antoine de Valle has no idea what to make of the exasperating, untrustworthy, and frustratingly beautiful woman he’s suddenly saddled with, but his honor demands he see Charlotte safely home. Especially since it’s his fault she accidentally witnesses his murder of a marquis, ends up on the wrong end of a brutal vampire death squad, and barely survives an encounter with the Beast of Gévaudan. In fact, the more Antoine tries to keep Charlotte safe, the more trouble they find themselves in. And the harder it is for Antoine to remember his honor in the face of Charlotte’s dangerous charms.
