If you thought blockbuster movies were the only form of entertainment that relied on over-the-top publicity stunts, you were wrong: It's alive and well in the book world as well. James Patterson's new thriller, Private Vegas, will not only be made available as 1,000 free digital copies that will self-delete after 24 hours. There will also be a one-of-a-kind physical copy wired to self-destruct after the same time frame.
