The Forgotten Child - A Riley Thomas Mystery, #1

The dead can speak. They need her to listen. Ever since Riley Thomas, reluctant medium extraordinaire, accidentally released a malevolent spirit from a Ouija board when she was thirteen, she's taken a hard pass on scary movies, haunted houses, and cemeteries. Twelve years later, when her best friend pressures her into spending a paranormal investigation weekend at the infamous Jordanville Ranch-former home of deceased serial killer Orin Jacobs-Riley's still not ready to accept that she can communicate with ghosts.
Shortly after their arrival at the ranch, the spirit of a little boy contacts Riley; a child who went missing-and was never found-in 1973. In order to put the young boy's spirit to rest, she has to come to grips with her ability. But how can she solve a mystery that happened a decade before she was born? Especially when someone who knows Orin's secrets wants to keep the truth buried-no matter the cost.
