A meticulous synthesis of history, science, and Ufology, "Heavenly Lights" establishes that the famed Fátima Incident of 1917 did not involve "Marian apparitions" - as is conventionally believed - but a series of close encounters with alien beings. The first history of the Fátima incident to be written by Portuguese historians based on the original documents of the case held in secrecy by the Catholic Church since the time of the apparitions, "Heavenly Lights" subjects all of the pertinent facts of the Fátima case to a sweeping evidentiary analysis that is at once thorough and fascinating. When it was fi rst published in Portugal in 1995, the Jornal de Notícias heralded this work as "a literary success without precedent." "Heavenly Lights" is Volume I of the Fátima Trilogy.
