Since House of Leaves was already suggested I won't suggest it again, but that is perhaps my favorite book of all time.

Clive Barker: Books of Blood, Damnation Game, Abarat (this one is a series that isn't finished yet, and it's a YA series, but it's still pretty good.)

Dean Koontz: 77 Shadow Street, Tick Tock, Odd Thomas (another great series), The Face, The Taken.

Derek Landry: The Skullduggery Pleasant series. (This is my favorite series of books, even more so than A Song of Fire and Ice.)

Chuck Palahniuk: Fight Club, Haunted, Choke.

Ellen Datlow: Any of her anthologies. She is an editor not an author, but she is a damn good editor.

Pretty much all of those recommendations are horror, if you want fantasy or mystery, I can give a few recommendations for those too.
