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.

Once, Frank Morgan had a wife and a future on the land - until a rich man with a grudge drove him out of Colorado.

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.

Deadwood, South Dakota. Miners flock there seeking fortunes, while cardsharps, bandits, and businessmen seek to deprive those who strike gold by means fair and foul.

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.
