Body Double by Hanna Johansson

As winter descends and the city fills with the scent of woodsmoke, a young transcriber follows the same routine each day. She collects tapes from a ghostwriter's office, stops for an espresso and croissant, and returns home to type out the voices of strangers - stories that will become someone else's novels. Her solitary life is predictable, unremarkable - until the day she hears something different on the tapes: a message meant only for her. Across the city, two women, Laura and Naomi, accidentally swap coats at a department store café. This brief encounter sparks something electric and strange, and soon, Laura has moved in with Naomi. As the days pass, she begins to mirror her more and more closely - her gestures, her habits, her very essence. Slowly, deliberately, Laura starts to take over Naomi's life. Meanwhile, the transcriber makes a disturbing discovery: she is beginning to disappear.
