MIAMI (AP) ― Stephenie Meyer’s “The Host’’ doesn’t have much in common with her Twilight series, except maybe the potential for a franchise.

Meyer is working on a sequel to the 2008 novel she began writing as an escape from the editing of “Eclipse,’’ the third book in the Twilight vampire saga. And now that it too has reached the big screen, she’s got more books in mind.

“Once you’ve created characters that have life to them, unless you kill them all, you know where their stories go. You’re always aware of what happens next,’’ Meyer told the Associated Press in an interview Tuesday. “I’ve got outlines for the next books. I would hope that this would be a three-book arc, but we’ll see.’’

At an advance screening of “The Host,’’ which premieres March 29, Meyer said she wrote the book when she was “kind of overwhelmed with vampires and red ink and a lot of people kind of having expectations of what they wanted from the next book and knowing that I wasn’t always answering those.’’

“The Host’’ trades the vampires and werewolves of Meyer’s previous works for space invaders. An alien race takes over the minds of their human hosts but leaves their bodies intact so that they can perfect the planet they believed humans were ruining. One human, a young woman named Melanie Stryder, refuses to give up her head space so easily.

Saoirse Ronan plays both Melanie and her alien invader in the film. Max Irons and Jake Abel play her love interests.

“The Host’’ will inevitably draw comparisons to the book and film series that made Meyer a phenomenon, but she hopes the story stands alone and appeals to a broader audience than just “Twi-hards.’’

For one thing, she calls it her “guy friendly’’ work because it explores bonds and loyalties beyond simple romantic love.

“When you’re a teenager, love feels like life and death, but this is actual life and death, which is kind of more fun,’’ Meyer told the Miami audience.

“Not to mention all the explosions and gunfire,’’ said Abel, who plays Ian O’Shea, one of the human rebels in the story.

What “The Host’’ does have in common with the Twilight saga is a love triangle, though one complicated further by two distinct entities sharing one body.

“Jake and Max call it the ‘love box,’’’ Meyer told AP.

Though she’s attracted to complicated relationships, that conflict probably won’t surface in the sequel she’s writing.
