Founded in 1866, The Frontier Overland Company was no ordinary stagecoach operation. To begin with, its founding partners met in a Wyoming saloon brawl. After a raucous burst of punching, cursing, and chair smashing, the last two men standing become friends for life. Two kindred souls with the same fighting spirit, Tucker Cobb and former Texas Ranger Butch Keeling agreed to launch a business together: a brand-new stagecoach line through the wilds of Wyoming . . .

Once upon a time in the Old West, Buck Trammel was a Pinkerton agent with a promising future. But after a tragic incident in a case gone wrong, he struck out for the wide-open spaces of Wichita, Kansas. Working as a bouncer at the Gilded Lily Saloon, he hopes to stay out of trouble. But soon enough, his gun skills are put to the test. The Bower gang shows up, turning a friendly card game with a Wyoming cattle baron into a killer-takes-all shooting match. Buck saves the cattle baron's life, but at the cost of two Bower men. That's when Deputy Wyatt Earp arrives.

He’s the son of a cattle rancher. A restless young dreamer who, under normal circumstances, would follow in his father’s footsteps. Normal, however, is not his style. Like his famous grandfather and namesake Perley Gates — a hell-raising mountain man with a heavenly name — young Perley wants adventure, excitement, and freedom. And like his grandfather before him, he will find his dream — in the untamed wilds of a lawless frontier. That dream, though, might just become a nightmare....

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.

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.
