Hunting Grounds

By L.T. Ryan and C.R. Gray

A killer’s return brings fear to Pittsburgh and draws the FBI into the hunt. Maddie Castle recognizes the threat from her own past, making every step of the investigation personal. Working with her K-9 partner, she has to balance the drive to stop him with the need to protect the people still in danger. Hunting Grounds brings the case painfully close to the investigator.
