Devil's Brigade (Trackdown Book 3) by Michael A. Black
A LIFE HANGS IN THE BALANCE, AND THE STAKES ARE DEADLY.
After having been court-martialed and sent to prison for a war crime he didn’t commit, former Army Ranger Steve Wolf has taken up bounty hunting with his friend, mentor, ex-Green Beret Big Jim McNamara. Having survived a brutal confrontation south of the border and a recent attack by mercenaries hired by his mysterious and incredibly wealthy foe, Wolf also finds himself being badgered by the FBI.
A lucrative bounty takes him and Mac to a lawless encampment inside a large city in the Pacific Northwest, but the same powerful, rich man who set Wolf up years ago is still shadowing him hoping to gain possession of a priceless artifact that is in Wolf’s unknowing possession. To accomplish this end, the sinister rich man employs still another professional killer, a former CIA fixer who is set to come at Wolf with unrelenting efficiency. Just when it seems things couldn’t get worse, Wolf and McNamara must suddenly rescue Mac’s grandson who has been taken to a militia compound and held hostage. Facing CIA killers, crazed militia forces, and overwhelming odds, Wolf once again finds himself outnumbered and outgunned.
