I kept wondering where this one was going. Was the MC a vampire himself? Was he a "hunter" (ala' "Van Helsing"). It is an interesting world the author has created here. I hope he writes further about this world.
On a side note: The thing about vampire and zombie stories that I can't seem to get past, even though I do enjoy them, the idea that if such creatures existed and given their abilities wouldn't humans be wiped out fairly quickly? I mean the ones they kill become undead too. So either way they win. Anybody else have this view?
Well, vampires for one always have distinct weaknesses. A human who learns these and how best to take advantage of them is more likely to survive. And if there's one thing humanity has proven itself adept at its adapting and surviving.
Zombies its a harder point to argue, cause it must be asked, 'What KIND of zombies?" now, if you're talking about '28 days later' "zombies", those do wipe out a good chunk of humanity before (spoilers)
starving to death. Now, these are only debatably zombies. But the principle of infection, at least, is in common with general zombie lore. I think this type of zombie would have a better chance of being the Doom of Humankind. But still - I think, as depicted in the movie, pockets of humanity could survive.
Some zombies are portrayed as slow and shambling. It seems to me this type would have a much lower chance of wiping out humanity. Even the ill prepared would have more time to acquire weaponry and defeat the hordes.
