After a family of four is crucified and burned alive, Jake Boulder is determined to help out his best friend and sometime-employer, a private detective related to the victims. But as Boulder tries to track the heinous killer, a young woman is abducted and found dead—and Boulder realizes these murders have something unusual in common. With virtually no leads for Boulder to follow, he strives to find a clue to the killer’s identity, but he’s not even sure if he’s hunting for one perpetrator or more. Then, after a young couple is snatched in the middle of the night, the FBI comes to Colorado to help with the case and Boulder is warned off. Still, he feels he has no choice but to press on when incendiary mobile-phone footage is sent to every major US news outlet—though it won’t be easy with the authorities against him—in this intense crime thriller by a #1 bestselling author.
