Much of the horror published today deals with supernatural forces, but nothing is more frightening than the unspeakable acts humans commit upon one another. Edited by Robert Bloch, the award-winning author of Psycho, this collection of works by such writers as Ray Bradbury, Ramsey Campbell, Jonathan Carroll, Charles Grant, and Richard Christian Matheson reveals the darkness of the human soul. For the first time in paperback, these seventeen stories explore the bounds of sanity and madness, and how easy it is for all of us to step over that line.
