Hans Holzer is a world-renowned parapsychologist and author of several paranormal books including Are You Psychic? and Ghosts, Hauntings & Possessions, in which we learn of Holzer's earlier forays into the world of the supernatural. His encounters with the undead are apparently never-ending. Ghosts: True Encounters with the World Beyond is a gigantic volume, documenting almost 200 cases of haunted houses, ships, castles, and just about any place imaginable! The cases are far more complex than just your average white-sheeted ghoul in the attic. Holzer examines the differences between "real ghosts," who reveal themselves to living people, and psychic impressions, which occur to many witnesses, always at the same time and place. There is also solid advice for interpreting paranormal signals--and even photographs of ghostly apparitions. This is an informative read, but one that is open to personal interpretation. --Naomi Gesinger
