Pekin Dewlap hasn't seen a ghost since she was twelve. But she'd do anything to get them back. Starting a ghostbusting business with her two best friends, Amber and Scout, seems like the perfect way to accomplish her goal. Of course, playing with ghosts isn't high on their wish list, so Pekin has to do some arm-twisting to get them on board.

Once committed, Pekin and her friends find themselves in deep, trying to solve the disappearance of fourteen-year old Miranda Talbert. Miranda went missing in 1918, and her spirit has wandered the halls of Elmwood Manor for the last hundred years.

In the midst of finding Miranda, discovering her budding feelings for Scout, and consoling a terrified Amber, Pekin is met by an angry ghost set on thwarting her plans. Will the Ghosties be able to help Miranda, or will Pekin's business die before she solves the mystery?
