The big-screen adaptation of Stephenie Meyer’s The Host doesn’t hit theaters till March 29, yet there’s already chatter that the Twilight author might turn this sci-fi thriller into a trilogy.

“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 earlier this week. “I’ve got outlines for the next books. I would hope that this would be a three-book arc, but we’ll see.”

Not so fast, cautions a source close to Meyer, who tells EW that there’s been no new news to report on the sequel/trilogy front. Besides, Meyer’s plate is pretty full at the moment — in addition to promoting The Host she’s a producer on the newly Sundance-acquired Austenland, starring Keri Russell.

Fans of The Host will have to make do with the movie for now: Saoirse Ronan (Hanna) plays Melanie Stryder, a rebellious young woman fighting for the human race who–after aliens invade and take over the minds and bodies of their human hosts–refuses to allow mind and spirit to be taken over and controlled. Max Irons and Jake Abel play dueling love interests. You can watch the trailer for The Host below.
