FORKS — When teenagers walk anywhere in Forks, a secret code seems to exist.

“Are you looking for Jacob or Edward?” Mike Gurling, office manager of the Forks Visitor Center, says to each as they walk in, as if it were a test.

Those in on the code emphatically name whichever Twilight character most holds their heart.

They are the dedicated fans of the teen phenomenon series of novels set in Forks.

The books, which tell the adventures of impassioned teens Bella Swan and her vampire boyfriend Edward Cullen, have remained top sellers since the first novel in the series, Twilight, was released in 2006.

“Oh my gosh, this is, like, my best birthday ever,” said Raven Morningstar, 14, dancing in glee with her best friend Alice Newberry, also 14, last week.

“When I first read the books, and saw that it was here — I had been here a long time ago — and was just so super-psyched because it was, like, ‘I have actually been there.'”

As a birthday trip, Morningstar, Newberry and Carina Morningstar, Raven’s mother, made the trip from Seattle to tour Forks’ Twilight sites.

The two 14-year-olds are avid fans and dedicated to their favorite characters — especially Edward Cullen.

Raven firmly believes that Bella will end up changed into a vampire in the end.

“But I think there will be a twist, and it will all end in a cliffhanger or something,” she said.
