Vincent Saint-Cyr is a mage-aristocrat and the owner of a club with a questionable reputation. Lilia Shackle, the daughter of a merchant, who has come with her family to a resort, has no reason to seek out such a man. Unfortunately, her younger brother has dragged the family into an adventure, and Vin is the only one who can help. The only trouble is that, for his services, Lord Saint-Cyr demands payment in kisses. What audacious insolence! But why—instead of tearing up the deal—does Lilia swoon at the touches of this unbearable lord, and why does he, it seems, have no idea that a modest old maid will not only upset his peace of mind, but also uncover a secret?
