In the early 1870's, the young state of Texas was struggling to survive. Its vast, undeveloped land of over 260 thousand square miles became a haven for the lawless. Murderers, rustlers and renegade bands of hostile Indians and Comanchero roamed the vast wastelands of west Texas with only a narrow river separating them from the sanctuary of Mexico. One group of dedicated lawmen stood between this element and the law-abiding citizenry - the Texas Rangers. This is the story of one of those men.

Sixteen-year-old Henry was ejected from the enormous St. Martin ranch and told never to return, or he would be shot on sight. He vowed to return and seek revenge against the entire family. When he finally returned, it wouldn’t be as Henry St. Martin, it would not be as a 16-year-old boy seeking justice for his mother, but as a hardened lawman with the name of Alex Paine.

Clay County Sheriff Rusty Price had been following the two killers since they galloped out of his town but kept out of sight until the sun set. In the low light, he closed the gap and planned to wait until they crawled into their bedrolls to take them down.

Mack Smith had left his shop in Pueblo and was just an hour or so from reaching his brother’s ranch for his annual visit when he felt the bullet slam into his head, and when his eyes finally opened, he found himself flat on his back on the bottom of a ravine. What the hell had happened? He was only a gunsmith, not a gunfighter.

Johnny Shooter was sentenced to hang at noon. But Judge Isaac Parker, widely known as the "Hanging Judge", made Johnny an offer he couldn't refuse. The judge made him a Deputy United State Marshal, then sent his new deputy after the worst-of-the-worst outlaws the Indian territory had to offer, with the orders not to burden the court by bringing them back for trial. Now, rumor has it that whenever outlaws gather around a campfire, the word is: "The only thing worse than standing before the Hanging Judge is hearing that Johnny Shooter is on your trail!"

After leaving his job as sheriff of Boulder, Sam Brown decides to visit his sister and her family on their ranch south of Denver, but discovers them all gone. He searches to find them, and what he discovers becomes his mission.

Was it justice... or revenge? What drove a simple farmer to set out on an impossible quest after a gang of bloodthirsty killers that raped and murdered his wife and slit his small son's throat? Their trail led him halfway across the country and deep into Mexico. One by one he tracked them down and brought them to justice, sometimes at the end of a short rope, more often in front of his fast guns, and he didn't care which.

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.

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.

Fifteen-year-old Joe Beck wasn’t listening as the minister eulogized his uncle but was already planning on what he would have to do as soon as they returned to the Quimby farm. He wasn’t welcome there even before his uncle had died and knew that his cousin John would soon order him to leave. While he had had a basic idea of where he would go after he left the farm, he didn’t know what he would do with the rest of his life.
