And you thought The Da Vinci Code was big!

Microsoft releases Halo 2 today for Xbox today, the sequel to one of the most popular sci-fi video games ever. Gates Inc. says the game will have "the highest first-day sales of any entertainment product in history, possibly topping $100 million." The game retails for $50 and they've already had pre-orders for more than 1.5 million units.

In book news, publisher Random House is printing an initial run of 1.1 million copies of the Halo 2 strategy guide, also for release today. That puts the book on par with the biggest of the big, matching the likes of John Grisham and Michael Crichton.

In related news, I am pleased to announce the upcoming release of my new book, Halo 2: The Mystery Series, to be published by Plagiarist Press.
