Re: What was the scariest and/or most disturbing book you have ever read?
The book that got me was Stephen King's Salems Lot, that book completely sucked me in.:)
Same here, it used to creep me out. Of course I had a habit of reading it while working the graveyard shift so I'm sure that didn't help.
2 of the better books I've found that are on the disturbing side are Fear Book by John L Byrne and Toy Cemetery by William W Johnstone.
