Outlaw falconer Nate Romanowski is off the grid and out for revenge in this riveting new novel from #1 New York Times bestseller C. J. Box. The campaign of destruction that Axel Soledad and Dallas Cates wreaked on Nate Romanowski and Joe Pickett left both men in tatters, but none more than Nate, who lost everything. Wondering if the civilized life left him vulnerable to attack, Nate dropped off the grid with his falcons in tow to rediscover his true self. And prepare for vengeance. When Joe gets a call from the governor asking for help finding his son-in-law who has gone missing in the Sierra Madre mountain range, he enlists the help of a local, a rookie game warden named Susan Kany. As Nate and Geronimo Jones circle closer to their prey, Joe and Susan follow the nearly-cold trail to Warm Springs. Little do Nate and Joe know that their separate journeys are about to converge…at Battle Mountain.
