Stateside fans of Meg author Steve Alten's Jurassic-shark novels can get an autographed poster of the book's really Great White if they order a copy of The Loch trade paperback from Amazon.com on Monday between 7 am and 9 pm. To receive the collectible, e-mail your receipt and (U.S.-only) street mailing address to meg82159@aol.com. Oh, and lest there be any confusion, the poster is signed by the writer, not by the shark.
