Disgraced attorney Andi Grey came to Alaska to find justice after a friend's murder. In order to find answers, she’s gone undercover in the dangerous world of ice road trucking.

Former CID investigator Duke McAllister is searching for his fiancée who disappeared two years ago on the Dalton Highway. Though the trail has gone cold, he hasn't given up hope he'll find her alive, along with the other women who’ve disappeared along the remote stretch of highway.

A snowstorm throws Andi and Duke together, and both of their plans come to a freezing halt. They’re stranded in the Arctic Circle, the only highway in and out of the area closed. While together, they discover a common true crime. When their favorite local Alaskan podcaster goes radio silent right before revealing the name of a cold case killer, they dive in to investigate only to make a terrifyingly frigid discovery.

Can these strangers work together to find answers before the biting, dangerous cold claims their lives? Or even worse . . . before the killer comes looking for his own brand of justice?
