A Texas Ranger pursues a deadly drug cartel through the badlands of Big Bend in this Western thriller by the Spur Award–winning author of Hawke's Target.

The serene beauty of West Texas's Big Bend National Park is shattered when four hikers are brutally ambushed by a sniper. Only one survives to report the murders. When investigators come up with nothing, they're left wondering if this is an isolated incident—or the beginning of a rampage. One week later, Texas Ranger Sonny Hawke heads into the park, determined to unearth the truth.

Before he knows it, he's in the same sniper's crosshairs. The drug and human smuggling cartel Coyotes Rabiosos—Rabid Coyotes—have lured him to remote backcountry, looking for payback for an old grudge. Wounded and stranded in the harsh desert terrain, Sonny is hunted, outnumbered, and about to become the target of an even more dangerous enemy—one whose thirst for revenge could incite an international conflict far beyond the U.S.-Mexican border.
