A deputy US Marshal battles a vengeful killer, domestic extremists, and her own dark demons in the breathtaking new installment of the Cady Maddix Mysteries.

Deputy US Marshal Cady Maddix assists a multi-agency operation by going undercover to infiltrate a group of domestic terrorists. Impersonating a fugitive she recently arrested, Cady attends a large multi-day gathering on an isolated private property in Georgia's Chattahoochee-Oconoee National Forest. Her target is Thad Coulson, the charismatic leader of a violent organization with plans of expansion that threaten the country.

Her assignment is two-fold—earn Coulson's trust and secure as much information about the participants as possible. She succeeds on both fronts but soon discovers that someone tracked her home and may have seen through her pretense.

While Cady engages in a dangerous game of deception, another more immediate threat draws closer. A killer intent on revenge has materialized from the shadows of her past and won't be satisfied until he exacts a gruesome retribution.
