trilogy, Dr. Jacques Vallee reexamines the historical record that led to the modern UFO phenomenon and to the belief in alien contact. He then tackles the enigma of abduction reports, which come from various times and various countries, as well as the psychic and spiritual components of the contact experience. In the last portion of the book, he notes the factors that inhibit research into the phenomenon--the triple coverup and political motivations--and concludes that the extraterrestrial theory is simply not strange enough to explain the facts.
