A meticulous synthesis of history, anthropology, and science, Heavenly Lights establishes that the F'tima incident of 1917 involved not "Marian" apparitions, as is conventionally understood, but rather a series of close encounters with alien beings. It does this by subjecting all of the available pertinent facts about F'tima to a sweeping evidentiary analysis that is at once very thorough and highly readable. In periodic digressions entitled "Parallels in UFOlogy," the authors draw many relevant connections between the facts of the F'tima incident and similar events in UFO history that have occurred at different times and places around the world. The text, which is rich in historical detail, speculative insight, and paranormal allure, is illustrated with dozens of drawings and diagrams that depict what actually occurred during the many events associated with the enigmatic F'tima incident. The book includes a Foreword by the eminent UFOlogist Dr. Jacques Vall'e that contrasts and compares "Marian" apparitions and close encounter cases, as well as relates his views about the transpersonal and spiritual dimensions of "alien contact."
