Paranormal Zones

The ghosts of Hollywood, the death of Edgar Allan Poe, the loving Martian, the Zone of Silence, cursed diamonds. Joslan F. Keller tells us eighteen disturbing stories that defy reason. Eighteen paranormal zones from around the world, all authentic and documented by the author, which shake our certainties-the unexplained phenomena in the sky, the incursions into the world of spirits, encounters with unusual characters, close encounters with UFOs, visits to disturbing places. Doesn't the improbable arise from our still-limited knowledge and our inability to rationally explain phenomena that go beyond our understanding? The world is neither black nor white.
Are there not an infinite number of grey areas, at the frontiers of the unknown, dominated by forces whose mechanisms are little explored, or not at all?
