Every Halloween, hundreds of highly controversial, religiously themed "Hell Houses" open their doors across Middle America. During the first night of a Texas high school's Hell House, a shocking and mysterious event occurs, leaving behind a small number of survivors. This motley crew is forced to battle their way out of the collapsing structure, while fighting against a terrifying and unspeakable force desperate to consume their very souls.
I picked up a copy of this at Half Price Books for a buck a few years ago and finally got around to cracking it open. Hell House is a quick read that can easily be described as Left Behind set inside of a haunted attraction.
