In this thrilling entry in Edgar Award finalist Paul Doiron's bestselling series, the death of Maine's last wild wolf leads Game Warden Mike Bowditch to an even bigger criminal conspiracy.

Warden Investigator Mike Bowditch already has a troubling mystery on his hands: finding the archer who mortally wounded Maine’s only wild wolf. Then he learns his best friend, Billy Cronk, has been released from prison after heroically defending a female guard from a stabbing. Mike comes to believe the assault was orchestrated by a wider criminal conspiracy. When the conspirators pursue Billy's wife and children to a “safe" cabin in the woods, Mike rushes to their defense only to find himself outnumbered, outgunned—and maybe out of options.
