Petrus Romanus, The Final Pope is Here"", Tom Horn, Christ Putnam.
I own this one and it came with a DVD chock full of referrence material - the actual documents scanned out from libraries I'll probably never visit. Awesome. The book says the last pope predicted in 1070, is about to emerge on the world scene, and all the prophecy associated with it.
In the middle of this, the library finally came up with Tom Horn's Nephilim Stargates, which I read in the middle of the other one. Fasinating stuff. Takes the position that as the earth approaches the equinox intersection with the Milky Way, stargates will open up and other entities will be visiting earth (again - he traces descriptions back to Summarian, Mayan, and other sources, which all seem to point to the date Dec. 21, 2012). Over and over again, he quotes the bible end times prophecy, "As it was in the days of Noah" which was the time the giants resulting from fallen angel/human women matings, and Mr. Horn's view is that the same will happen again when the "others" (Watchers) return this time.
He also takes the view that some nephilim survived the flood and their descendents embody evil in high places here and now. I guess L Ron Hubbard and someone else tried to have spiritualist events to invite the others back. At least that is cited in the book. Very interesting. It seems the 2nd half of Petrus Romanus rehashes some of this. The first half is mostly history of the various Popes and the nature of the papacy (mostly bad) in the interveneing years between the prphecy (Malachi prophecy) and Pope Benedict - the current one, (XVI?) Anyway, the next pope will be "Peter the Roman" according to prophecy and he will bring destruction to Rome.
