Way of the Wolf
This is not your same-old bloodsucker novel. I imagine it has a scifi genre label is due to the nature of the vampire itself. In the world that Knight has created, a race of DNA-altering beings called the Lifeweavers were able to spread throughout the universe via the Interworld tree. This portal/gateway system was created by an older form of beings that existed before the Lifeweavers called the Pre-entities. These Pre-entities existed by living off of the 'life-auras' of different species, making them almost immortal through the process. The Pre-entities traveled around through the tree that they built feeding off of species on different planets, even visiting the earth in our pre-history (wiping out the dinosaurs).
Eventually the Lifeweavers discovered how to use the Interworld tree for themselves. They can change their appearance at will, by manipulating their DNA, and appeared to our ancestors as gods and avatars. They were peaceful, and were mostly here to help, not only Earth but other planets. On a planet called Kur, some of the Lifeweavers were able to discover the secret to near-immortality by studying relics from the Pre-entities. These Kurians (as the vampires are called) then traveled to Earth over the centuries. With their various creations they created the myth of the vampire by feeding on the 'life auras' of humans. But never in an organized fashion. Eventually they came to earth in force, and gained positions of power around the world, by disguising themselves in human form. They orchestrated the eventual downfall of the human race, by manipulating governments, the economy, etc. Then they assumed command of the World and instituted their New World Order in roughly 2022.
The interesting thing of the story is that the other Lifeweavers, those not on the planet Kur, are outraged by the treachery of the Kurians and their betrayal of their code, which was to not hurt anyone. They have been waging a war against the Kurians over the galaxy by using the Interworld Tree. Earth, as it is now, is only one of the fronts for that battle. But it is the subject of the books, of course.
The Lifeweavers use humans as their weapons in the war. Not many of the humans know this. There are freeholds within Kurian-held territory, where humans can defend themselves against the Kurians and live freely. The defensive forces are mostly Guards, who protect. There are three highly advanced groups of forces who take the battle to the enemy. All three have met with one of the Lifeweavers and have had certain 'potential' within themselves turned on by the Lifeweaver's manipulation of their DNA. They are still human but have acquired special traits like heightened senses and stamina. The three groups are Wolves, Cats and Bears.
Wolves are the most numerous and enter enemy territory in small assault groups to hit them where they are vulnerable and then run. They are basically guerilla troops.
Cats work alone in enemy territory, often gathering information, or sabotaging them.
Bears are a stand-up fighting unit. They willing engage enemy forces, and are the real power of the humans.
The cool thing about the Vampires is that they never touch their victims to take their 'life auras.' Through their ability to manipulate DNA, they have developed Reapers. Reapers are basically all of the worst features of Nazgul and Velociraptor in one package. They are super killing machines who live off of the blood of their victims. They have a scaled, sharp tongue which they stab through their victims neck to suck blood out of the heart. While they live off of the blood, the Kurian lord who controls them, acquires the 'life aura' to sustain his own life.
The Kurian lords control certain territories. However, they fight against each other for power, and control of certain industries or land. Within a certain area, there are groups of humans, called Quislings, who work for the Kurians and police their fellow humans. They are basic scum, each trying to earn a brass ring, by selling out other humans. The brass ring is given by a Kurian lord and ensures that they won't be food for that lord, and gives them protection against other Kurians. The Quislings do things like round up vagrants and send them to the Kurians for lunch. There are bounty hunters who go out and hunt humans to sell to the Kurians.
The Kurians don't do any fighting themselves. They are like big mob bosses whose underlings do all of the dirty work. The Reapers are able to sense 'life aura' and go out and hunt people in the Free zones. The Wolves and Guards are in place to stop that. The Wolves can avoid the Reapers by learning to suppress how much 'life aura' they are producing and can escape from rough situations that way.
The Wolves will rarely be able to fight a Reaper and win. Only in full daylight, or when the Reaper has just taken a meal and is listless can they hope to face them in a fight. The Reaper has a skeleton of 'carbonite' (or so they call it, remarking they think the provenance of the word comes from 'some old movie') which renders it difficult to attack. The robes that they wear are bullet-resistant. The only way to kill them is to sever the head (not a stake through the heart).
Since the Kurians can manipulate DNA they also have another host of baddies that can be called into action against the Rogue humans.
At any rate, not your standard vampire novel. I found it very interesting that Knight was able to present his vampires in a context of the vampire mythos and the history of the planet in a way that was logically consistent. That overtime the separate beings of Kurian and Reaper eventually merged into one Dracula-esque being who is usually portrayed in the culture.
I found it appealing because it took a conventional trope of the horror genre and added a scifi spin which is, to my knowledge, unique to this series.
