This is news to us, but apparently there's this thing called 'Twilight'; it's a series of books (from some author that we've never heard of named Stephenie Meyer) about Bella Swan, a teenage girl caught in a love triangle with these two mysterious guys. But get this, one of the guys Jacob Black is actually a werewolf, and the other, Edward Cullen, is a vampire. Totally crazy, right? Well these 'Twilight' books must be pretty popular because they made a whole bunch of movies based on them and they've all made lots of money. We're talking hundreds of millions of dollars!
