What will you do after you finish the fight in Halo 3?  You could read Halo Effect, a new book that explores the Halo world and beyond (don't miss the free preview chapter at the previous link).

Now, in Halo Effect, science fiction authors, scientists, critics, and even fellow gamers explore Halo’s hold on players and its influence on the world of gaming. What’s behind the helmet of the superhuman Master Chief is a mystery. What’s behind Halo is the story of the most popular video game of all time.

The good folks at BenBella Books have been kind enough to offer up three copies of Halo Effect to PTB readers which means that it's time for another contest.  To enter just send an e-mail to [email protected] that includes the answer to this trivia question: What was the codename of the final testing version of Halo 3?  Three entries will be chosen at random from the correct answers, and all entries must be received by 11:59pm ET on September 30, 2007.  And now the customary rules and caveats.  Contest open only to those with North American mailing addresses, PTB is not responsible for lost or misdelivered entries, winners will be notified to provide a mailing address for prize delivery which will then be turned over to BenBella Books who will send out the books, winners will be announced on October 1, 2007, are you a bad enough dude to rescue the president?  Good luck!
