The tale of a sleepover where a vengeful ghost is the uninvited guest who won't leave ... or let anyone else leave. It was supposed to be a normal winter sleepover. Hot chocolate and pillow forts and scary movies. But Maria's friends had other things in mind. They bring out a board game that is supposed to help you talk to the dead, and Maria wants nothing more than to communicate with her recently deceased sister, Isabella. She gets her wish. Isabella responds. And in the days that follow, it becomes clear that Isabella isn't the sweet girl she was in life.
