A New York Times Bestselling Author When two sisters set out across a remote stretch of Montana road to visit their friend, little do they know it will be the last time anyone might hear from them. The girls ? and their car ? simply vanish. Former police investigator Cody Hoyt has just lost his job and fallen off the wagon. Convinced by his son and his former rookie partner, Cassie Dewell, he begins the drive south to the girls? last known location. As Cody makes his way to the lonely stretch of Montana highway where they went missing, Cassie discovers that Gracie and Danielle Sullivan aren?t the first girls who have disappeared in this area. This majestic landscape is the hunting ground for a killer whose viciousness is outmatched only by his intelligence. And he might not be working alone.
