Likely the most dangerous cult in the US today is the cult of Ron Paul (which of course is much enamored with his dear son Rand). The cult of Ron Paul quotes mostly only two authors; their cult leader himself (often in youtube format) and his idol Ayn Rand. Now their second-favorite messiah has new scripture coming out: http://www.usatoday.com/story/life/books/2014/12/04/lost-ayn-rand-novel-to-be-published/19885893. Well, actually it is old scripture - written in 1934 to be precise - but it is text from Alisa Rosenbaum (the real name of Ayn Rand) that very few have ever seen. The rediscovery of "Ideal" in 2012 has lead to its being prepared for publication next July.
We can almost certainly expect to hear a lot more "libertarian" declarations next year once this starts gaining traction.
