As "Twilight" celebrates its last-ever Comic-Con, the book inspired by Edward and Bella's love affair, the much kinkier "Fifty Shades of Grey," is making waves as it debuts. By all accounts, the book's premiere at the annual festival has been quite massive.

According to The Hollywood Reporter, fans lined up early for the Thursday afternoon book signing and the chance to meet the woman behind the phenomenon, E L James. Within one hour, all 300 tickets had been snapped up. The report also notes that a majority of those there to get their books signed by James didn't look like typical Comic-Con fans. Instead, they were older women, with a few men sprinkled in.

In an interview with U-T San Diego, James opened up about heading to the city for all the Comic-Con madness. "I love the craziness of Comic-Con," she said. "Last time I was there, I met a friend at a small plaza nearby. And she was in amongst lots of zombies. We felt like we were in zombie land. It was surreal and a lot of fun."

She later noted that she was looking forward to meeting "Fifty Shades" devotees. "It's so lovely to meet people who enjoy your story," she said. "It's a real joy."

After her Thursday signing, James tweeted about her experience, which included getting the chance to meet fans of that other beloved book series. She wrote, "COMIC CON!!!! Fav moments so far #SDCC: Shooting the breeze with twihard pals at CampTwilight, signing & meeting lovely readers & partying last night."

As for her own devotion to "Twilight," James told U-T San Diego, "Yes, it started as fan fiction. I was completely inspired by the 'Twilight' series to write. I am a fierce Twihard. I think of both ('Shades' and 'Twilight') as 'Beauty and the Beast' kind of stories. They stem from that side of fiction."

It doesn't seem likely, however, that "The Twilight Saga" author Stephenie Meyer will ever read the book she inadvertently spawned. "That's really not the kind of stuff I read," she told MTV News on Thursday. "It's awesome. I think she's here. I hope she's having fun."

And how does Edward Cullen himself feel about reading the books? Well, Robert Pattinson joked that if he ever does read them, "I'd just sit there and lick the pages."
