Nightmare — S.K. Epperson

On a remote ranch deep in the Flint Hills at a clinic for women diagnosed with multiple personality disorder, patients are dying in extremely violent ways. The staff has invited Dr. Bryan Raleigh and his team, along with his journalist brother, David, to write about the clinic, and from the moment of their arrival they begin to unravel secrets about the family that owns the ranch, including a strange blood ritual practiced by the hemophiliac son and even more bizarre rites performed by the grotesque, voyeuristic wife of the clinic's director. Soon David and the others begin to suspect the rude, imperious woman who never leaves the third floor may be somehow responsible for the deaths of traumatized patients dying one by one, and the closer they get to the truth, the bigger the threat becomes to their own safety.
