You beg the principal to reconsider, only to be told that George hasn't been expelled. Because there is, and was, no George. Who is lying? Who is real? Who is in danger? Who is in control? As you search for answers, the anonymous calls begin a stranger, who insists that you and she share a traumatic past and a guilty secret. And then the caller threatens your life.
