I just read The Keep again by F. Paul Wilson.

Plot synopsis:

"Something is murdering my men." Thus reads the message received from a Nazi commander stationed in a small castle high in the remote Transylvanian Alps. And when an elite SS extermination squad is dispatched to solve the problem, the men find a something that's both powerful and terrifying. Invisible and silent, the enemy selects one victim per night, leaving the bloodless and mutilated corpses behind to terrify its future victims. Panicked, the Nazis bring in a local expert on folklore--who just happens to be Jewish--to shed some light on the mysterious happenings. And unbeknownst to anyone, there is another visitor on his way--a man who awoke from a nightmare and immediately set out to meet his destiny.

The battle has begun: On one side, the ultimate evil created by man, and on the other...the unthinkable, unstoppable, unknowing terror that man has inevitably awakened.

Edit: Looks some of it's available to read on-line at google books. http://books.google.com/books?id=mKXl8j_oZeMC

The Keep is great. Read it. I'm reading The Hellbound Heart by Clive Barker now. It's the book the first Hellraiser movie was based on and it's pretty good. Quick and easy. I'd also recommend Darkly Dreaming Dexter, and that's all I can think of right now.

Yeah I can't wait for The Scarlet Gospels to come out, apparently it might be years before it comes out.

H.P Lovecraft collected stories especially At the Mountains of Madness:

Basically the only fiction I read is mostly horror besides select authors I like.

Plot Synopsis:
The story is written in first-person perspective by the geologist William Dyer, a professor from Miskatonic University. He writes to disclose hitherto unknown and closely kept secrets in the hope that he can deter a planned and much publicized scientific expedition to Antarctica. On a previous expedition there, a party of scholars from Miskatonic University, led by Dyer, discovered fantastic and horrific ruins and a dangerous secret beyond a range of mountains taller than the Himalaya.

The group that discovered and crossed the mountains found the remains of fourteen ancient life forms, completely unknown to science and unidentifiable as either plants or animals, after discovering an underground cave while boring for ice cores. Six of the specimens seem to be badly damaged, the others uncannily pristine. Their highly-evolved features are problematic: their stratum location puts them at a point on the geologic time scale much too early for such features to have naturally evolved yet. Because of their resemblance to creatures of myth mentioned in the Necronomicon, they are dubbed the "Elder Things"

Lots of his stuff is free on-line including At the Mountains of Madness. There are tons of great HP Lovecraft stories, but this is one of his best.
