Battle Mountain is the 25th installment in C.J. Box's acclaimed Joe Pickett series, published by G.P. Putnam's Sons (a Penguin imprint) in February 2025. This hardcover mystery thriller follows Wyoming game warden Joe Pickett as he ventures into the Sierra Madre mountains at the governor's request to locate a missing son-in-law, accompanied by rookie warden Susan Kany.

Running parallel to Joe's investigation, outlaw falconer Nate Romanowski has dropped off the grid with his falcons to rediscover himself—and to seek vengeance. As both storylines unfold across rugged Western terrain, they converge at Battle Mountain in a dramatic conclusion that tests the limits of loyalty, justice, and survival.

A New York Times bestselling series, Battle Mountain delivers the fast-paced action, sharp dialogue, and authentic Wyoming wilderness detail that fans of C.J. Box have come to expect. Available in hardcover (368 pages) and paperback formats.
