The Twilight Saga publishers from Brazil, China, France, Germany, Italy, Mexico, Taiwan and the UK will also be participating. The selected fan from each country will receive an advance copy of The Official Illustrated Guide and get to talk extensively with Meyer, who will answer their Twilight-related questions.
The contest started January 12th, and goes until February 12, 11:59 EST.
You can enter for the contest on the website. currently there are only links for the US and Canada, but there is a note that the other countries will be up there soon!
