"I want redemption for Katrina. She starts so dark, I would hate for her to also finish dark," Aoki says of the book's ending. "The part that but hidden under there, the part that's real is almost too real," she adds about this sci-fi urban fantasy novel. 'We're not going to sugarcoat it,' writer and producer Dylan O'Brien tells CNN.
