When a charred body is discovered in a shallow grave on the ridge, officer Mattie Cobb and her K-9 partner Robo are called in to spearhead the investigation. On a rugged Colorado mountain ridge, Mattie Cobb and her police dog partner Robo make a grisly discovery-and become the targets of a ruthless killer.Ĭolorado's Redstone Ridge is a place of extraordinary beauty, but this rugged mountain wilderness harbors a horrifying secret. But when Robo does catch her scent, it leads them to information that challenges everything they thought they knew about the case. Grasping at straws, Mattie and Robo follow a phoned-in tip into the dense forest, where they hope to find a trace of the girl and rescue her alive. It seems that someone has snatched all trace of the Walker girl from their midst, including her scent. Knowing that each hour a child remains missing lessens the probability of finding her alive, Mattie and Robo lead the hunt while Cole and community volunteers join in to search everything-to no avail. But that’s only the start of trouble in Timber Creek, because soon another girl goes missing-and this time it’s one of Cole’s daughters. When she and her K-9 partner, Robo, get called to track a missing junior high student, they find the girl dead on Smoker’s Hill behind the high school, and Mattie must head to the Walker home to break the bad news.

By the time they find her body, the storm has broken and the snow is coming down hard. But it's mid-October and a dark snow storm is brewing over the high country-and they're already too late. When Deputy Ken Brody's sweetheart goes missing in the mountains outside Timber Creek, Mattie Cobb and Robo are called to search.
