Valentino is still in a sort of self imposed isolation after his fight with the demon manticore, in which he revealed his true nature to those closest to him. But he can't cut himself off forever, and the impending visit by vampire royals combined with the mysterious death of a high society young woman means that Valentino must resume his duties as both a detective and consort to the Guardian Aladar.
In a world where faeries, vampires, shifters and other supernatural creates have revealed themselves to be real, Valentino is the human “consort” to the guardian of Philadelphia, a high ranking supernatural charged with keeping the peace with humans. Valentino enjoyed his relationship with his guardian, but she is called back to the land of the fae to assume the crown as queen. Her replacement is a vampire, and Valentino takes an instant dislike to the man.
