"I can't answer it." That was the non-answer "Twilight" author Stephenie Meyer gave in bonus footage from her appearance on the "Oprah Winfrey Show" when asked if there might one day be a fifth book in the series.

"The way I write is ... it's what makes me happy," she said. "I can't write when I feel like people are looking over my shoulder. So I have to tell myself that this book I'm not going to publish. It's only for me, it's never going to leave my computer and I have to really believe that to be able to work on it."

Meyer admits she's "a little burnt out" on vampires right now, so she's planning to take a break to spend some time with her aliens, i.e. the characters from her first sci-fi book, last year's "The Host."

Though she didn't address what, if anything, might become of the aborted "Midnight Sun" novel told from the perspective of "Twilight" protagonist Edward Cullen, she did tell Oprah that she originally had a different ending in mind for "New Moon." Meyer also said she knows exactly what happens to Bella and Edward — she's just not going to tell anyone at the moment.

"I might do something completely different — I've got to cleanse the palette," she said of her next endeavor. "I might come back to it. I did envision it as a longer series, but I wrapped up 'Breaking Dawn' in a way that I felt satisfied with."

Meyer said she might also break in a different direction and follow her muse to a "totally fantasy" novel she described as completely unrelated to anything she's done before, and so fantastical that it requires a map in the front of the book just to navigate the magical realm.

Calling "The Host" her favorite thing she's done so far, Meyer said she envisioned it as a trilogy, and so she's busy thinking about that at the moment, as well as the upcoming movie adaptation of that saga.

"I had grown a lot as a writer by the time I got around to writing it," she said of "The Host" in explaining her deep affection for the book about the alien race, Souls, and their dogged quest to take over the mind of untamed spirit Mel Stryder. "I think it's better. 'Twilight' ... I was so raw. I could do it so much better right now. I'd love to go back and rewrite that one and do a director's cut."

With "New Moon" about to hit theaters, Meyer said she was worried about the film adaptation of the second book in the series, fearing that it would be the most difficult one to translate to the big screen. "I thought that 'New Moon' would be the most problematical movie we'd have on our hands because it is so internal," she said. "This heroine is having hallucinations about someone she's lost. I mean, it's tricky. Lucky for us, [director] Chris Weitz is a genius."

Some of Meyer's favorite moments in the movie are new scenes that Weitz suggested. "It would always be something so beautiful and so in line with how I see the characters," she said, noting that Weitz would walk around the set with the "New Moon" book under his arm.
