London strangles beneath a thick blanket of yellow fog. The noxious vapours muffle all sound, conceal any who dare to venture out of doors, hide lovers and criminals alike.
Felicia Lamb, innocent, delights in the fog-bound night. She seeks the world beyond life -- and will embrace death to find it.
Reginald Callendar, Felicia's fiancé, stalks the darkened streets, searching for his bride-to-be and the vampire who stole her. If he must, he will track them to the ends of the earth.
Sebastian Newcastle, once Don Sebastian de Villanueva, is a demon darker than death itself. He does not fear Callender's vengeance -- what harm can a mortal bring to one of the undead?
