Iris Johansen and Roy Johansen team up for another page-turning thriller as investigator Kendra Michaels is drawn into the FBI's case against a prolific serial killer who is about to reveal the location of his numerous victims.

After scoring a plea deal in a high-profile murder trial, serial killer James Michael Barrett leads a grim parade of law enforcement officers to the body of his last victim. At the alleged burial site, the officers swing their shovels down and are met with a strange metallic sound they weren’t expecting. In a blink, a terrific explosion rocks the woods, killing Barrett and most of the officers instantly. The detonation is only the beginning of a shocking case for FBI consultant Kendra Michaels—a string of heinous murders in the style of the very-dead Barrett mysteriously continue, and it becomes clear that he may not have been working alone. As the crimes accelerate, Kendra reluctantly accepts help from college student Tricia Walton, the only survivor of Barrett’s attacks. But the killer has a terrifying plan that Kendra and her team are only beginning to understand.
