Here is the startling proof-in one comprehensive, eye-opening volume. Brad Steiger, the world-renowned authority on unexplained phenomena, presents a collection of UFO encounters and abductions. His provocative theories provide answers to the most puzzling questions: Why are they here? What do they want? And how will they change the fate of the human race? Included here are stories of airplane disappearances, alien experimentation, close encounters of the alien-sexual kind, and hybrid children. Alternately entertaining and terrifying, this is a book for anyone who has gazed into the night sky and wondered if we are alone in the universe. "Brad Steiger's book does an excellent-indeed, essential-job of setting the scene and providing a foundation of the facts as they were known at the time it was written. It is to be hoped that, in time, this provocative and disturbing reality will come into ever greater focus." -Whitley Strieber, from the foreword
