I'm in the mood for Scary

I'm feeling like I need a really good scary story to read. HAs anyone read anything lately that has you staying up at night scared stiff? I'm a spook junkie.

I'm reading The Descent by Jeff Long. (I LOVE the movie by the way.) The book has kept me up at night reading; it's really interesting. There is also a sequel, Deeper, by the same author. I haven't finished the first one yet, but I've already bought the second one. It's definitely a good read if you want something scary!
