What is the scariest book ever written?

Almost anything written by Stephen King and some of Edgar Allan Poe's work has been known to cause nightmares also.


The one story that gives me chills every time I read it is called The Mist. It's a short story written by Stephen King and will soon be out in theaters.

Personally, the book that I have read that was thought of as a horror was Winnie the pooh hundred acre woods the owl made me soil myself.
