Peppermill, those books are still available and in stock! I just had to search around a little. They seem to sell out so quickly at barnes&noble, which is a bummer, but try amazon and/or books-a-million for his stuff.
Exposing the Hidden Things and Exposed World - you need to read these next.
Encounter at North Road House is coming out in about a month or so. This is a greatly anticipated horror story about a masked psycho who enters a haunted house looking for a victim, but initially the masked psycho doesn't know that the house is haunted. The ghosts of the haunted house lock shut the doors and entrap the masked psychopath. Can't wait for this one to come out - a must get - look out for it!
