Click here to read about a very cool new project that Yen Press is working on: Twilight: The Graphic Novel. The newest issue of Entertainment Weekly (hitting newsstands on Friday) will feature three exclusive illustrations from the book. More information about the book, including the publication date, will be coming. This is the first announcement of the book, so it is still not available for pre-order, but I will post a link as soon as it goes on sale.
