What happens when a human being becomes possessed by Satan? What are the horrors of being possessed? What type of man is an exorcist? Why would he offer himself as hostage to the devil so as to free the person possessed by evil? What are the physical tortures and mental anguish of the exorcist? Here for the first time, in a book of unforgettable power and compassion that is being praised as a milestone by churchmen of varied faiths, are documented case histories of possession and exorcism -- the real life dramas of five Americans whose exorcisms were performed between 1965 and 1974. - Jacket flap.
