In the lawless expanse of 1850s Kansas Territory, justice rides on the fastest draw—and nobody draws faster than Conner Smith.

At twenty-five, Conner carries the weight of the frontier on his shoulders. A federal marshal commissioned to bring order to chaos, he's earned a reputation as the deadliest lawman west of the Missouri River. But when stagecoach bandits murder Patrick Sullivan during a brazen daylight robbery, Conner's hunt for the McCall gang becomes personal—for the victim's sister, Mary Sullivan, is about to change everything he thought he knew about the life he's chosen.

The McCall Gang: Five Men, One Price on Their Heads

Brothers Thomas, William, and Charley McCall, along with cousin Silas and Comanche tracker Running Wolf, have terrorized the territory for three years. Banks, stagecoaches, homesteads—nothing is safe when they ride. When they vanish with $5,000 in stolen money and leave two dead behind, Conner's pursuit spans a thousand miles of unforgiving country.

Through blistering Kansas summers and bone-chilling winters, Conner tracks them across:

• The rugged Smoky Hills, where a desperate outlaw leads him on a three-hour chase before a 300-yard rifle shot ends it
• Palo Duro Canyon's hidden caves, where dynamite and courage bring down a killer who's never surrendered
• Mexican borderlands, where stolen gold and ancient secrets test Conner's resolve
• Indian Territory's lawless expanse, where Hacksaw Jim's gang waits in the shadows

A Marshal. A Woman. A Choice.

Mary Sullivan never imagined she'd fall for a lawman. Men like Conner Smith don't settle down—they ride off into legend and never come back. But as Conner's pursuit drags on month after month, Mary finds herself hoping against hope that the fastest gun in the West might finally have found something worth staying for.

When Conner finally corners Charley McCall at a remote trading post, the showdown that follows will be talked about in saloons for generations.
