You'd think the big day for vampires this year would have been Halloween, when a whole lot of bloodsuckers were roaming the streets freely and without impediment.

If you thought that, though, "Twilight" is clearly not on your undead radar.

The popular young adult book series by Stephenie Meyer focuses on a beautiful young misfit named Bella Swan and the gorgeous, brooding love of her teenage life, Edward Cullen, who inconveniently turns out to be a vampire torn between his desire for sucking face and sucking blood.

The books - there are four of them - have already spawned one hit movie released in 2008 and made big tabloid celebrities out of its attractive stars, the prettily pouty Kristen Stewart and square-jawed brooder Robert Pattison. (It doesn't hurt the gorgeous actors are rumored to be an item.) The second movie, "New Moon,'' was released last week.

For those with "Twilight" bloodlust - mostly teenage girls, teen-at-heart grown women and fans of all things sci-fi - the release of "New Moon" was a bigger deal than any "Star Wars" prequel or "Harry Potter" film (or Halloween, for that matter).

In "New Moon," fans of the book know, they'll finally get to see some major Bella/Edward moments, including a painful breakup scene once bloodthirsty Edward realizes he must leave Bella to protect her life.

The new movie also includes Bella's 18th birthday party, teen wolves, cliff diving, a troublesome love triangle and the introduction of a dangerous and frightening new group of supernatural bad guys, the Volturi.

There also will be, predictably, a lot of blood - blood letting, bloodlusting and blood-pumping bloodthirstiness.
