The Redemption Series — Nancy Jackson

With Christmas on the horizon, they call OSBI agents Carrie Border and Lainey Tate to a case in Southeastern Oklahoma. The area is home to the legendary Robber's Cave in the center of dense forest, cliffs, and mountains.

Local law enforcement have found three burned bodies and turn to the OSBI for help in finding the killer. Carrie and Lainey fall into false leads and backwoods locals who do not want their nefarious crimes revealed.

The agents fight nature itself to find a killer who seems lost in the expanse of forest and caves while navigating treacherous obstacles in order to do their job. Neither are strangers to danger and terror, but this case, with the odds stacked against them, may cause them to face their own deaths.
