'Twilight: New Moon' is the best-selling book of 2009. Surprised?

The Twihards have spoken: Edward and Jacob aren't just in demand on the big screen but in the bookstores as well.

All four of Stephenie Meyer's "Twilight" books topped USA Today's best-selling books of 2009 list.

Which book was No. 1? "New Moon" of course! The film adaptation of the book was released in November 2009, but the "Twilight" fandemonium began way before the film came out.
