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, especially Nate, who lost almost everything. Wondering if the civilized life left him vulnerable to attack, Nate dropped off the grid with his falcons in tow, to 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 fellow falconer 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.

The Reviews Are Coming…

“Box is the master of landscape writing, with the reader feeling the chill of the outdoors and smelling the pine trees. He has delivered a gut-punching thriller that is both compelling and brutal in this cataclysmic war between good and evil. This series gets better with each installment.”

—Jeff Ayers, firstCLUE

“You know you’re in for a wild ride . . .  [Another] must-read, preferably in one sitting.”
