Coldheart Canyon is both one of his goriest and sexiest novels. I definitely recommend it, especially if you're into the history of film.
PS: I'm reading Cabal right now, which belongs to the Books of Blood series. The title story, which the film (directed by Barker himself) Nightbreed was based off of, was a fun read that surpassed the film in many aspects, but the true highlight thus far is The Life of Death. I really can't wait to read The Last Illlusion, which the also-Barker directed film Lord of Illusions was derived from. Lots of goodness!
