What do you do when somebody targets one of your own?Alone on the couch one night, Reed and his partner are both summoned to the hospital to find two of their colleagues have been viciously attacked, left for dead on the side of the road with very little evidence to go on. With emotions high and the entire department vowing revenge, Captain Grimes assigns the case to Reed and Billie, offering them any resources available in finding the culprit.What was at first seems just an isolated incident soon begins to spiral as more bodies are found, strewn across the greater Columbus area from Grove City to New Albany. Each victim appears to be somehow linked to the law enforcement community, though how or why they have been chosen continues to elude Reed as he is joined on the case by Cassidy Glenn from the state's Bureau of Criminal Investigation.Together they work their way from one scene to the next, piecing together what seems to be driving this perpetrator in their vendetta, hoping to bring things together enough to get out ahead of them before anybody else falls victim.
