Battle Mountain (Joe Pickett #25) by C. J. Box, 2025. Hardcover.

The campaign of hate and vengeance that a pair of violent criminals wreaked on Wyoming Game Warden Joe Pickett and his friend, falconer Nate Romanowski, left both men in tatters, but it was Nate who came closest to losing everything.

Facing his lowest ebb, Nate decided the only option was to drop out of society. Taking only his birds, he went off-grid to rediscover his true self… and prepare for his own revenge.

When Joe is called on to help the governor, whose son-in-law is missing in the Sierra Madre mountains, the investigation takes a darker turn when Joe and Nate's very different journeys unexpectedly converge.

All will come to a head at Battle Mountain, but in a struggle neither of them would ever have seen coming, can both Joe and Nate survive?
