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.

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.

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.

Ashford had gathered an army of criminals and renegade soldiers, leading them on a path of destruction and kidnapping through Texas to the Gulf. Among Ashford’s captives were the Travens’ sister and Dal’s tough-minded fiancée, Kate. Now Mac and Dal must take up arms once again and ride together against Ashford’s army.

Eighteen-year-old Garrett Shaw and his father spotted the rustlers and pulled their Winchesters. They kept their muzzles pointed away from the three men who were stealing eight steers from their small ranch to give them a chance to leave peaceably. When they started throwing lead, Garrett and his father began returning fire. Garrett hit one of the rustlers just as his father’s horse went down. Hours later, as the doctor examined his father’s injury, Garrett knew that it was now his responsibility to provide for his crippled father, mother, and sisters.

US Deputy Marshal Earl Crawford had just entered the office after returning from a typically Texan assignment where bullets flew like dirt in a twister. He hadn’t even hung his hat when the boss approached him about an even more dangerous mission, but only if he chose to accept the job. Normally, he wasn’t given the choice, but in this case, even though he could have turned it down, he knew that he had to go.

Doc Holt listened to the boys at the other end of the bunkhouse as they joked about the night’s excitement, and he felt sick. What they were doing bothered him. Why they were doing it bothered him. But most of all, why he wasn’t doing anything to stop it bothered him.
