1870. A time known as The Great Killing. The vampire clans arose and slaughtered humanity with unprecedented carnage in the northern parts of the world. Millions perished; millions were turned into herd animals. The great industrialized civilizations of the world were left in ruin. A remnant fled south to the safety of the ever present heat which was intolerable to vampires. There, blending with the local peoples, they rebuilt their societies founded on human ingenuity, steam and iron.
Set in a postapocalyptic world, this tale of courage, sacrifice, and heroism takes place against the backdrop of an age of steam and rational humanism, where the social elite have rejected religion and spiritualism as nothing more than quaint superstition. Brutal Vampire Clans rule half the world, keeping human herds for food, and Princess Adele, heir to the throne of Equatoria, is faced with grim choices. War is imminent and her marriage to the odious Senator Clark of America will cement an alliance uniting the Equatorian Empire and the American Republic.
