The author of Twilight, Stephenie Meyer, is working on a screen adaptation of her sci-fi novel The Host.
The book, very much like Meyer's Twilight series, involves a love triangle. Set in a world where alien body snatchers rule Earth, an alien is fused with a dying woman in a bid to hunt the last remaining man on the planet - only to find the woman falling in love with him.
Gattaca's Andrew Niccol will write and direct the film.
Producer Nick Wechsler said, "We wanted Stephenie to be involved in the adaptation and have her endorse and be part of the creative decisions. Twilight has proved she knows more about what works than most."
