The Apocalypse, but it's been a long time so I only base loosely just 'cuz (unless it is a WoD game). Vague is good enough in this case.
I had a friend who loved LKH when she read the first few books and told me I needed to read them. I like vampires too, but depends greatly on the verse their from. Anyway yeah, later books she dropped it too. Too much of one thing can ruin anything. :)
