A detective's fall from grace. A rookie's baptism by fire. A town's secrets laid bare.

In the unforgiving wilderness of Maine, a disgraced detective must confront his past to solve a chilling murder.

Detective Brock Justice's career is on thin ice. Once the golden boy of Maine State Police, Brock now finds himself exiled to the remote northeastern wilderness, punishment for crossing the thin blue line. Assigned to the Major Crimes Unit—North, he suffers the added indignity of partnering with newly-minted Detective Chloe Wright, a rookie with her own hidden struggles.

The pair's uneasy alliance is put to the test almost immediately when a routine snowmobile retrieval in the coastal town of Blue Hill unexpectedly escalates into a full-blown murder investigation. Even as the case exposes the darkest corners of the town, their fragile partnership threatens to undermine the investigation at every turn.

Brock and Chloe's hunt draws them into the lives of several intriguing locals: the town doctor, a biker gang involved in drug trafficking, a politically connected sheriff, and Brock's own father. With each revelation, the line between ally and enemy blurs, compelling Brock and Chloe to question their trust in everyone around them, including each other.

Even as winter's icy grip loosens from Blue Hill, the noose of suspicion tightens. Brock must navigate not only a shaky partnership and a town harboring deadly secrets, but also the shadows of his own past. Can he and Chloe piece together the puzzle before Maine's wilderness swallows them whole?

Retired Detective Sergeant Bruce Robert Coffin delivers a masterful blend of police procedural and small-town intrigue. Perfect for fans of Craig Johnson's Longmire series and C.J. Box's Joe Pickett novels.
