Kevin Falzon is a Maltese writer who has written seven books(a) including two on the subject of ancient astronauts and their interaction with humans. He closely follows the theories of the late Zecharia Sitchin and blends them with the even more outlandish ideas of Hubert Zeitlmair. However, his credibility as a serious researcher is further damaged by his support for a conspiracy theory that has the ‘Illuminati’ responsible for the killing of celebrities such as Kurt Cobain, Princess Diana, James Dean, Marilyn Monroe and Amy Winehouse among many others[869.381]!
Falzon is apparently unaware of Adam Weishaupt (1748-1830) who founded the ‘Illuminati’ in the 18th century(b) and who witnessed its demise early in the 19th century. There is no evidence that it lasted in any meaningful way after that.
Falzon identifies Malta as a key part of Atlantis.
Hank Harrison (1941- ) is an American writer and publisher and sometimes better known as the father of the singer, Courtney Love and father-in-law of the late Kurt Cobain. Among a range of subjects he has expressed great interest in Megalithic Europe in two of his books, The Stones of Ancient Ireland(a) and Finding Atlantis. In the latter, he supports the idea of a megalithic Atlantis with its centre of power probably located in the Morbihan area of Brittany.
>In The Cauldron and the Grail  Harrison focuses on the cultural background of the megalith builders. His instincts told him that many of the important sites had both a functional purpose an astronomical predictors and as early religious centres.<
Another recent book by Harrison is Arthur the God(b).
