Downloading Ghostly Findings (Ghostly Book 2) E.M. Leya

As a medical examiner, seeing ghosts has its advantages. After being informed by a ghost that there is a mass grave in the area, Lance and Detective Angus Young feel the fallout. As one investigates the murders, the other investigates the bodies, both trying to piece together what happened. Luckily, the dead aren't all silent. As ghosts of the victims appear, clues to what happened start to come together. The only problem now is figuring out who the killer is and catching him before he strikes again.
