Jonas Peters and Frank Sanders team up to solve a string of murders, starting with the intentional and fatal bombing of the Common Grounds, a local coffee sharp in downtown Riverside - a mostly calm city in Southern California. Dozens are dead after an explosion rips apart the Common Grounds, leaving dozens of others gravely injured. Frank soon finds himself up to his elbows assisting the vombing victims, especially when he discovers that Jonas was on of the injured, who had been on his way to neet his fiancee. In an instant both Frank's and Jonas's lives are thrust into a trail of death and destruction carried out by an unknown psychopath.
