Barkun discusses a range of material--involving inner-earth caves, government black helicopters, alien abductions, secret New World Order cabals, and much more--that few realize exists in our culture. Looking closely at the manifestions of these ideas in a wide range of literature and source material from religious and political literature, to New Age and UFO publications, to popular culture phenomena such as The X-Files, and to websites, radio programs, and more, Barkun finds that America is in the throes of an unrivaled period of millennarian activity. His book underscores the importance of understanding why this phenomenon is now spreading into more mainstream segments of American culture.
