It's no surprise that the inseparable Ace and Chance Jensen have a knack for taking risks - even if they have to blast their way out of them. Chance is a bit of a hothead, good with his gun and his fists. Ace is more of a thinker, sharp as a snake bite and just as deadly quick.

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

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 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.

With Apaches on the prod, ex-cavalry sergeant Sean Keegan, bounty hunter Jed Breen, and ex-Texas Ranger Matt McCulloch take shelter in a West Texas way station - along with a hot-as-a-pistol female bound for the gallows, a spiteful newspaper editor, and a coward with $50,000 who promises them five grand if they'll deliver his blood-soaked stash to his wife. Turns out, Indians might be the least of the problems for the trio, soon to be known as the Jackals. The loot's stolen property of the vengeful Hawkin gang, and these prairie rats are merciless, stone-cold killers.
