In his younger days, Taylor Callahan didn’t know right from wrong—and didn’t much care either. As a Confederate bushwhacker, renegade outlaw, and all-around hellraiser, he gave the devil himself a run for his money. Somewhere along the road to perdition, he decided to change his wicked ways. To atone for his sins. So he became a traveling preacher. But Taylor Callahan is no ordinary preacher. He rides the Western circuit looking to help lost souls. His mission of peace takes a violent turn when he enters the godforsaken town of Falstaff, Texas.

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.

After a lifetime of robbing banks and holding up trains, Jimmy "Slash" Braddock and Melvin "Pecos Kid" Baker are ready to call it quits, though not completely by choice. Sold out by their old gang, they have to bust out of jail and pull one last job to finance their early retirement. The target is a rancher's payroll train. Catch is: the train is carrying a Gatling gun and 20 deputy US marshals who know they're coming. Caught and quickly sentenced to hang, their old enemy - the wheelchair-bound, bucket of mean, Marshal L. C. Bledsoe - shows up at the last minute to spare their lives.

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.

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.
