Stephenie Meyer has a lot to be excited about. "Breaking Dawn - Part 2," the final installment of her "Twilight" vampire saga, hits theaters later this year, and the author has already started on her next big-screen project. She is currently working [article id="1685927"]on the set of "The Host,"[/article] the film adaptation of her sci-fi romance novel.

When MTV News headed to Albuquerque, New Mexico, for a behind-the-scenes look at the movie, Meyer told us how strange it feels not to have "Twilight" stars Robert Pattinson and Kristen Stewart hanging around on set.

"It makes it a lot calmer. I do miss them, though," she said. "It seems funny not to have Kristen here. 'I'm on a set, why can't I talk to Kristen?' That's a little funny."

Although she misses working with the actors she spent nearly five years with bringing Edward Cullen and Bella Swan to life, Meyer has welcomed the experience of filming "The Host." Along with giving audiences the chance to see a whole new cast of characters, it was an opportunity to escape the dark and gloomy weather in Forks. "This [set] has beautiful landscapes everywhere we've been, and so that's been kind of different, too," she said. "We're not in a forest where you can't really see. We've got all this beautiful stuff. It's great."

She particularly enjoyed filming on the cave sets. "It was so awesome. The cave set was enormous. It was vast," the writer said. "They're just so cool, so much fun to walk on. It was kind of like someone built something out of your imagination just for you."

Meyer's story follows the invasion of an alien race called Souls. They enter the human body like parasites, erasing their hosts'

personalities. But when Melanie Stryder's (Saoirse Ronan) body snatcher, Wanderer, instead becomes engulfed in Melanie's memories, she develops her own feelings for Melanie's love Jared (Max Irons) and allies with her host body to find him.

Those of you wondering if the script will stay true to the book needn't worry; the story is in good hands. Meyer revealed she's had a lot of input in this film thanks to director Andrew Niccol.

"Andrew and I work pretty well together. He's really, really great, and so he was super-easy to work with," she said. "In the script-writing process he loved to hear what I had to say and worked really well with me on that. He's really about, 'What do you think about this? What do you think about that?' I think [I have more input] because we are really in sync."

If you're like Meyer and you too miss Stewart and Pattinson, tune in to MTV on Sunday, June 3, at 9 p.m. ET for the
