Two of the Johnstones’ most legendary heroes—the rugged mountain man known as Preacher and the Scottish clan rancher Jamie Ian MacCallister, here together for the first time—are forced to choose sides in a blood-soaked battle for the heart and soul of a nation divided. This is not the American dream they were looking for. This is a nightmare. A brutal, blood-drenched frontier war that two heroic men must fight and win—or one struggling nation will never come together. For liberty and justice for all.

Sheriff Joe Brooks was talking to a young prisoner who gave him some incredibly bad news. Three notorious gangs of outlaws had merged into one large band big enough to take over entire towns in his sparsely populated county. It was when they began to terrorize his county that he had to act, and he’d have to take them on alone.

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.

Flint Moran was fourteen years old when the Civil War ended. He was fifteen when his family bought a plot of land near Tinhorn, Texas. He was barely nineteen when he caught a pair of rustlers stealing cattle—and singlehandedly brought them to justice. How did a teenaged boy track down and capture two hardcase thieves without any help? That's what Tinhorn sheriff Buck Jackson wants to know. He can't help but be impressed by Flint's sharp eye and natural talent with a Henry rifle. So he offers to deputize the boy—tin badge, Colt Frontier Six-Shooter, and all—and Flint happily accepts.

As a young man, John Bannack worked hard on his brother's farm—until times got tough and his brother grew desperate. Desperate enough to rob a bank. Unfortunately, John's brother left a trail that led straight to the Bannack farm. When a posse showed up to make an arrest, John made a fateful decision: He confessed to his brother's crime. Sacrificed his freedom for the sake of his brother's family. And doomed himself to a hard, hellish life in a rat-hole state prison.
