Hmmm. On the verge of her 18th birthday, Miley Cyrus may be taking a step into the darkness. The Disney princess is attached to star in an adaptation of Lisa McMann’s young-adult paranormal thriller novel Wake for Paramount Pictures and MTV Films, which are picking up film rights to the property. Disturbia co-writer Christopher Landon will adapt the book for the screen. Wake is the first of three novels written by McMann about a 17-year-old girl named Janie with the unwanted ability to become sucked into people’s dreams. Not surprisingly, she sees things she would rather not see. But when she gets pulled into a terrible nightmare, Janie dangerously goes from mere witness to participant. The edgy sequels, “Fade” and “Gone,” detail her investigations with boyfriend Cabel into the perverse activities of teachers at their school and the difficult fate that lies ahead for her. Paramount and MTV Films are grabbing rights to the entire series — all of which have been New York Times best-sellers — with the desire to spark a franchise.
