(AP Photo/J. Scott Applewhite, File) (Newser) – A mystery is sweeping Washington: Who penned the forthcoming O: A Presidential Novel? The 368-page, $25.99 book, out for release Jan. 25, is about the Obama administration—and is reportedly written by an anonymous author who has “vast personal experience” with the subject, the Washington Post reports. Early rumors pointed to Joe Klein, the journalist who penned Primary Colors, a similar, initially anonymous, book about the Clinton campaign. But in an exchange with Yahoo! News, Klein says he really, really didn't write this one.
