Lady Felicity Ferkloth never imagined that she could live a real, dangerous adventure. And yet, this happens when a mysterious stranger invades her apartment and makes her a particularly tempting offer: to secure her marriage to a sought-after duke. Such a marriage may have been Felicity Ferkloth's dream, but she is determined to accept only under one condition. She has heard and read many beautiful stories overflowing with passion and she would like to experience great love.
The mysterious intruder is known as the Devil. Illegitimate son of a duke and now undisputed king of London's dark streets, he has desired power his whole life, seizing opportunities and crushing his enemies. As it seems, Felicity Ferkloth is exactly what he needs to take the revenge he has been plotting for years. All he has to do is transform the innocent angel into an irresistible temptation, set his trap, and destroy his enemy.
However, the Devil, in the midst of his fierce desire, has overlooked a minuscule detail; that even the best-laid plans have a weakness capable of making them collapse like a house of cards.
