A lot of people are familiar with "The Devil Rides Out" film and book though it certainly polarizes opinion some love them some hate them.

The King in Yellow by Robert W. Chambers. A book I found so disquieting I can't even bear to own a copy.

Hmmm Deja vu

The Wasp Factory by Iain Banks-the scariest book I've ever read-pure unadulterrated horror of the most chilling form. Be warned this book will mess with your head!

Favorite horror book?
 

My favorite horror book is really an anthology of ghost stories named TRUE GHOSTS compiled and edited by ANDREW HONIGMAN.

Favorite horror book!
 

Mercury de Brus is definitely my favorite horror book. It is extremely powerful and very well-written. It's a story about a women who's the head of a family that fights to protect mankind from be possessed by risers (demons) who are looking for the fifth pentacle of mercury. If they find it they will devour all humans and eventually take over everything. There is action, some sci fi, suspense, love and torture. It's a wild ride from start to finish and the author, C.E. Scott, describes the characters and their surroundings with a imagery that is nothing short of amazing. There are a few teaser chapters and a full length download on amazon.com or kindle store. I strongly urge anyone reading this to check it out. You will not be disappointed. The book is so much more than horror, to classify it on one genre would be an insult.

Usher's Passing
 

Likely Usher's Passing by Robert R. McCammon

That was a disturbing book, but a good read none the less.

I am Legend by Richard Matheson, The Long Walk by Stephen King, The Shining by Stephen King, Heart-Shaped Box by Joe Hill, Interview with the Vampire, I know it's just a novella, but Mephisto in Onyx by Harlan Ellison was pretty amazing.

I hated The Long Walk. What a waste of time that book was

Seriously?! That was my favorite story in that book.
