Alien Agenda is the silk thread leading the way through the maze of UFO literature into the heart of the UFO controversy. While he begins with the premise that the existence of UFOs cannot be denied, Jim Marrs (author of Crossfire, the mother of all John F. Kennedy assassination conspiracy books) boldly strides into the battle over what UFOs are and why they are here. Marrs's investigative skills are invaluable in this re-examination of questions that have been overlooked, unaddressed, or unsatisfactorily resolved.
