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.

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.

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.

Matt Jensen, reared by legendary mountain hero Smoke, is the last of a proud breed. He will soon learn that dispensing justice with a gun is the only true way to execute righteous revenge in the Old West.

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.
