Ghost Writer — Chanel Smith

In Ghost Writer, Chanel Smith's seventh installment in the Ghost Files series, Ellen's friend and neighbor, Diana, reports hearing noises in her apartment from a possible intruder, but no one has broken in. The police are stumped. Ellen senses that Diana, a single mom, may be experiencing paranormal activity. Upon investigation, It seems that an old manual typewriter-typing by itself-is being operated by a ghostly writer who has a message for Diana. But it's not just a message from the past. It's a message from her own past.
