Reading List - What Scared the $#!@! Out of You?

What are you reading, or have you read recently, as far as horror short story collections go, that really knocked your socks off? I have been staying up late picking through old editions of the Mammoth Book of Horror, volumes 1 - 4, and there are plenty of good scares in there, and  I am picking up Joyce Carol Oates' new book Corn Maiden and other Terrors from the library soon, but I like to keep my bedside piled dangerously high with "to read" selections so am looking for more, much more. Also recently finished John Langan's Mr. Gaunt and other Tales. (Meh.) Primarily interested in short story collections, but if you have a novel that you consider a "must read" lay it on me.
