The four novels of the Twilight series by Stephenie Meyers present a vampire-themed love triangle involving Bella, a human, and her love interests, a good vampire named Edward and a werewolf named Jacob. The four novels have garnered a devoted following of young adults since the publication of the first book in 2005. By October 2010, 116 million books had been sold worldwide. The saga inspired a series of five feature-length movies beginning with "Twliight" in 2008. The last of the movies will be released in 2012. The first four movies of the series have generated more than $2 billion in revenues. The books and movies have launched the production and sale of a variety of Twilight-related toys, clothing, and other consumer goods. Only one question remains: In your heart of hearts, are you Team Edward or Team Jacob?
