mine was:

'Storming the Gate, the Horrible Discovery of Professor Sims.'

talk about intense, the thing has teeth.

it used to be 'The Exorcist' until about a month ago though....

Scariest book.
 

Ya, probly the Exorsist. However, It by Steven King was not only epic but, scary as all hell. I also recamend, Floting Dragon by Peter Straub.

Prey by Graham Masterson. A very, very disturbing book.

Book
 

Have to agree with knife fight, the short King story the boogyman got to me. Still hate closets to this day! HA!

the stand made me uncomfortable and no one could calm me down for a week, same with stephen's it.

but scariest? Dracula.

i don't read books about satanism or anything, or books like pet sematary, etc, because they make me very uncomfortable, and i don't like that.
