The first book-to-film transition seemed to work pretty well for Twilight author Stephanie Meyer, so she’s giving it another go round with The Host.

Deadline reports that Lovely Bones actress Saoirse Ronan has been cast in the role of Melanie Stryder in the film adaptation of the best-selling book series.

So, what exactly goes down in the sci-fi book?

The Host is about alien parasites who take over people’s bodiess, and Saoirse’s character is one of the last humans around who fights against the species referred to as “Souls.”

The film will be written by Now screenwriter Andrew Niccol. No word on when production would start or a release date.
