Need any more evidence that World of Warcraft has gone mainstream? Arthas, the latest expanded universe novel about none other than our own Lich King (that got rave reviews from our own writers), has reached number 16 on the New York Times bestseller list for hardcover fiction. We're sure that makes Christie Golden happy -- I don't believe that any Warcraft-related novels have ever made the list before. Rise of the Horde is the most popular one I can think of, and I don't think that appeared there on first release. It's not the only videogame-related book of fiction to make the NYT, though -- the latest Halo novel did that a few years ago.
At any rate, just shows you how popular the Warcraft universe really is, even outside of the videogame audience. You can pick up the Arthas book at a bookstore near you, or order it up from Amazon as well.
