Very much a horror story. Travelers trapped in a "haunted" house
that will not let them escape. Supernatural beings abound and they all want to kill the travelers. The authors are Christian ones, but there is no attempt to impart any religious dogma. The house as an allegory for people's struggles in the dark and evil inclinations is implied, but the outcome of the story and the fate of the characters remain a mystery to the end. The book is creepy, scary, and sure makes one want to walk in the light.
