Matt Bardoul was a good man to have as a friend and a bad one to make trouble with. He was also a single-minded drifter—until he met his match in an outspoken beauty named Jacquine Coyle.

After Matt signs on to join them, he discovers that there is a group of outlaws in the party—gunfighters and thieves that Matt wouldn’t trust for a minute.

The great state of Texas is a land of opportunity. For outlaws. And horse thieves. And cattle rustlers. Not to mention bank robbers, train robbers, and anything-that-ain’t-nailed-down robbers. The state’s governor, Richard B. Hubbard, is at the end of his rope. He wants to clean up Texas once and for all—and he’s desperate enough to try something crazy: hire a man who can do what the Texas Rangers can’t. A man not tied down by a wife or children. Or rules. Who’s not afraid to go outside the law.

As a decorated undercover DEA special agent, Garrett Kohl has traveled the world - and fought in most of it - but it’s the High Plains of northwest Texas he calls home and dreams of returning to one day. Kohl is in the middle of an assignment in Afghanistan when his commander orders him back to Texas on a short mission expected to take a week at most. But Kohl is unsettled to discover that he’s moving from one kind of war to another.

Holt’s latest job is in Devil’s Gulch in Colorado Territory. But wiping out bands of bank robbers is just the beginning. More disorder is brewing, and the skittish mayor has handpicked Holt as the new sheriff. Holt is what the town needs: a mercenary with a badge, a loaded Remington, and a deadeye-aim for trouble. Devil’s Gulch has the vigilance committee. The man behind it—Joe Mullen, the largest rancher and mine owner in the valley—isn’t keen on an outsider like Holt muscling in on a good thing. Mullen already has his hand in all the crime in Devil’s Gulch.

And with nothing left to lose, he's the last man who will ever back down....

He left the West at the age of seventeen, leaving behind a rootless past and a bloody trail of violence. In the East he became one of the wealthiest financiers in America—and one of the most feared and hated. Now, suffering from incurable cancer, he has come back to New Mexico to die 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.

Joe Pickett is the new game warden in Twelve Sleep, Wyoming, a town where nearly everyone hunts and the game warden—especially one like Joe who won't take bribes or look the other way—is far from popular. When he finds a local hunting outfitter dead, splayed out on the woodpile behind his state-owned home, he takes it personally. There had to be a reason that the outfitter, with whom he's had run-ins before, chose his backyard, his woodpile to die in.

The Witch's medicine was bad. She must be killed. But she ran before they could act. She ran across the Dakota prairie until she could run no more. She turned and faced the oncoming warriors. She had no hope, yet she would defy them until the end. Then, came the thunder.

Now there's nowhere left for William and Annie to hide…and no one they can trust. Until they meet Jess Rawlins.

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.
