Black gold and blood don't mix well on the Nueces.
Having hung up his badge and kept his promise to Cassie, Texas Ranger Lucas Dunn, Jr. is building something new-a life, a legacy, and a future beneath the South Texas sky. But when oil erupts on the ranch, so does the violence that seems to follow Junior wherever he rides. Apache warrior Tochin strikes the drilling site with savage fury, triggering a blowout that turns fortune into catastrophe.
Junior barely douses the flames before a deeper treachery surfaces. His own oil manager has vanished with the profits-and the trail leads straight into a ruthless crime syndicate bleeding the oil fields dry. No badge. No backup. Just a man who knows what justice looks like.
As crude ambition collides with frontier law, Junior must decide how far he'll ride when everything he's built is at stake. Death doesn't care if you've retired.
