The last days of the Civil War. With Richmond under siege, Confederate soldier Luke Jensen is assigned the task of smuggling gold out of the city before the Yankees get their hands on it — when he is ambushed and robbed by four deserters, shot in the back, and left for dead. Taken in by a Georgia farmer and his beautiful daughter, Luke is nursed back to health. Though crippled, he hopes to reunite with his long-lost brother Smoke, but a growing romance keeps him on the farm.

Once a respected lawman in Kansas and Oklahoma, Ty Brannigan ended his career as town marshal of Warknife while he was still young enough to marry, start a family, and raise cattle. Now nearly sixty, he’s a proud husband, father of four, and proprietor of the Powderhorn Ranch. He’s more content wrangling cows than criminals. But for every outlaw Brannigan put in jail, noosed, or left to the vultures, he made even more enemies. They’ve made the mistake of targeting his wife and children—only to discover that Ty Brannigan enforces his own law with a lightning-fast draw.

The great state of Texas is a land of opportunity. For outlaws. And horse thieves. And cattle rustlers. Not to mention bank robbers, train robbers, and anything-that-ain’t-nailed-down robbers. The state’s governor, Richard B. Hubbard, is at the end of his rope. He wants to clean up Texas once and for all—and he’s desperate enough to try something crazy: hire a man who can do what the Texas Rangers can’t. A man not tied down by a wife or children. Or rules. Who’s not afraid to go outside the law.

It’s 1852. The wounds of the Mexican War are healing. Regis Royle, co-owner of a steamship fleet, has made it out alive, relatively unscarred and with enough profit and foolhardy ambition to envision a new life in south Texas. With the help of his crack-shot kid brother Shepley, his glad-handing riverboat partner Cormac Delany, and his old friend, raw-edged former Texas Ranger Jarvis “Bone” McGraw, Regis is laying claim to the prime jewel in a magnificent rolling prairie: the Santa Calina range teeming with wild mustangs, cattle, and eighteen-thousand acres of lush promise.

A killer is on the loose in the Arizona Territory. One by one, Tonto Basin ranchers are being murdered for their livestock - and the Cattle Raisers' Association has hired two range detectives to catch the culprit. From the looks of them, Stovepipe Stewart and Wilbur Coleman are just another pair of high-plains drifters. But with their razor-sharp detective skills and rare talent for trouble, they're the last remaining hope for one young cowboy who's been arrested for the murders. Stovepipe and Wilbur believe the boy is innocent.
