Cuno Massey may be a federal fugitive, but he’s Deputy US Marshal Spurr Morgan’s best chance to run down a gang of gunrunners. A wagon train of rifles, ammunition, Gatling guns, and dynamite was stolen by US Cavalry deserters who intend to sell the weapons to a Mexican general waging war against Yaqui Indians. To even the odds against them, Cuno and Spurr form an alliance with Ojos de Fuega — “Fire Eyes” — a Yaqui queen as savage as she is beautiful, and her band of renegades.

Wagon trains carrying immigrants along the Oregon Trail are falling prey to outlaws. Most families surrender their valuables and goods peacefully, but anybody brave enough to resist gets a bullet. The gang's latest victim was a wagon master who sought to protect his charges only to die in the dust. With the blood of good men being spilled and families being terrorized, Preacher and Jamie MacCallister volunteer to escort the next wagon train. Their odyssey across the unforgiving territory takes them through violent storms and into the sights of hostile Indians.

Cuno Massey killed those deputy US marshals all right, but only because they were about to rape the women he was escorting to safety. Thrown into a federal penitentiary, he faces a death sentence - until the beautiful Camilla and her cutthroat gang bust him out and head for the Mexican border. Pursued by lawmen as brutal as the desperadoes he travels with, Cuno rides a bloody trail, unsure where his allegiances lie, and wondering if he was better off waiting for the gallows....

Cuno Massey had always stayed on the good side of the law. But he’d never found himself stuck in the middle of a feud between a weary old rancher and a band of Indians hungry for revenge. With warring braves surrounding the ranch and a doomed man begging for help, Cuno’s the only rider left who stands a chance to save the rancher’s daughter from a savage massacre.

To get out of jail, Yakima Henry accepts a proposition from the wealthy Mr. Cleve O'Shannon and his wife. They need a hard man to lead them through a bloody hell to save their family - and their fortune. For his freedom, Henry agrees. But freedom won't matter if he's not alive to enjoy it....

Half-white, half-Cheyenne Yakima Henry has been ambushed and badly injured. Bleeding to death, he doesn't know who'll get to him first: the gunslingers or hungry wolves. Thankfully, comely widow Aubrey Coffin comes along and drags Yakima to safety. But as he heals, lawless desperados circle closer to finish the job they started by putting his innocent savior in the cross fire.

When bounty hunter Lou Prophet and his partner Louisa Bona capture a gang of stage-robbers, they haul their quarry to a remote town to get their due. But Bitter Creek proves even more dangerous than hunting outlaws when Sam Scanlon and his murderous riders hang all the lawmen. Now, Lou Prophet is going to show them that justice doesn't always wear a badge.

Lou Prophet loves to keep beautiful women company. But when the invitation comes from Miss Louisa Bonaventure, the Vengeance Queen, he finds himself intimate with hot lead instead of her warm female form. Louisa’s got him riding the brutal Mexican frontier chasing outlaws led by Tony Lazzaro, a notorious thief whose deadly weapon, Sugar Delphi, is a blind and blood-hungry pistolera.

Most of bounty hunter Lou Prophet’s man-hunting jobs have been purely business transactions that he’s carried out with cool professionalism. He’s seldom seen the depravations his quarries have committed to earn a price on their heads. But when the Red River Gang raids the town of Luther Falls, Prophet witnesses it in person - and can’t do a thing to stop it. It’ll be days before anyone can organize a posse - and a small girl has been kidnapped by the cold-blooded outlaws. Prophet will have to go it alone.

Lou Prophet is in mixed company these days. He doesn’t mind being close to his pretty pistol-packing partner, Louisa Bonaventure. Known as the Vengeance Queen, she has his back — and dare he say it, part of his heart. But accompanying the vile outlaw Blanco Metalious back to Nugget Town to see him hang isn’t exactly Lou’s idea of a good time.

Cuno Massey is determined to start a new, peaceful life. But when he comes across a prison wagon under attack, he can’t just ride on. A gang of outlaws is hell-bent on granting four hardened convicts an early release, and with two other lawmen down, the marshal is badly outnumbered. Dispensing frontier justice from the barrel of his Colt .45, Cuno does his best to even the odds and keep the murderous animals where they belong — in their cage. But the trail is long, and the gang is relentless. Looks like Cuno has just signed on for the ride of his life.

Lou Prophet's life as a bounty hunter has taught him one rule: You don't stop riding 'til the job is finished. Louisa Bonaventure gives that rule a whole new meaning. After seeing her family slaughtered by Dave Duvall and his Red River Gang, she and Prophet have tracked down and wiped out every last murderer - except for Duvall. 

He may be a Confederate turned-bounty-hunter with a predilection for trouble, but Lou Prophet knows you never overstay your welcome in a town that wants you dead. Now, all because a young fool with a lousy poker hand couldn’t hold his temper, Prophet has a bloodthirsty posse aiming to pump him full of lead for murdering the son of prominent cattleman Gerard Loomis.

Sheriff Ben Stillman knows that every lawman could face sudden death. But that doesn't ease his anger over Marshal Charlie Boomhauer's brutal murder. And ol’ Charlie's shoes have already been filled by his brash, young deputy - who isn't exactly out shaking the bushes to find Charlie's killer or killers. The new marshal is blaming the murder on a band of Gypsies who moved north - or was it south?

It’s hard living on the Colorado frontier — especially when you’ve got a bounty on your head. Ever since Cuno Massey killed Vince Evans, the no-good son of wealthy rancher Franklin Evans, men have been hunting his head for its sizeable bounty. Men like the big bear of a bounty hunter, Ruben Pacheca, the most fearsome tracker of them all, who robs and rapes as he hunts. And it’s anyone’s guess whether Cuno’s new love, a sassy outlaw named Marlene, will be his savior or his destruction in beautiful disguise....
