Down Range (Garrett Kohl #1) by Taylor Moore
As a decorated undercover DEA special agent, Garrett Kohl has traveled the world—and fought in most of it—but it’s the High Plains of northwest Texas he calls home and dreams of returning to one day. Kohl is in the middle of an assignment in Afghanistan when his commander orders him back to Texas on a short mission expected to take a week at most. But Kohl is unsettled to discover that he’s moving from one kind of war to another.
The once-peaceful ranching community he loves is under attack by a band of criminals who have infiltrated law enforcement and corrupted local businesses, and are now terrorizing Kohl’s own family. Hoping to prevent bloodshed, Kohl tries to resolve matters peacefully. But when the group strikes first, he has no choice but to go on the attack.
Unfortunately for the crew of criminals, Garrett Kohl, besides being an elite undercover officer for the DEA, is a battle-hardened Green Beret who spent the better part of his career hunting terrorists. Although outnumbered and outgunned, Kohl knows the wild and forsaken Llano Estacado region of Texas better than anyone. And like so many trespassers before them, these murderers will find out the hard way that the only thing tougher than this land is the people who call it home.
