Dark Horse Books (you know, those guys) have allied with Nintendo and will be publishing The Legend of Zelda: Hyrule Historia, an "unparalleled" historical account of the beloved Zelda series. The book has been available for some time now, but only in Japanese -- this version will of course be presented in English.
Featured in the 272 page hardcover book: new concept art, an official chronology, complete history, in-depth development information, an introduction by Shiggy, an exclusive comic by Akira Himekawa, and more.
Unfortunately you'll have to wait awhile to get it: it ships January 29. The price: a reasonable $34.99.
