When forty-one successful manhunts make you a legend, there’s only one way left to go—down.
J.J. Westin, the infamous Rustler Hunter, goes undercover at Arizona Territory's largest cattle ranch to expose the rustlers bleeding it dry. The thieves aren't just stealing cattle. They're trusted cowboys operating from inside the bunkhouse.
What he doesn't expect is Hayley Harper, the tough-as-nails cook with secrets of her own. She's a Pinkerton agent working the same case and the daughter of notorious outlaw Galen Harper.
When their covers are blown, they uncover something far deadlier than rustling. A corruption network spanning three territories. With enemies closing in and bullets flying, the legendary manhunter and the outlaw's daughter must survive the badlands of 1898 Arizona, where trust is deadly and justice comes at gunpoint.
In the shadow of Canyon Diablo, where the historic Aztec Land & Cattle Company's Hashknife outfit controlled over a million acres of the Arizona Territory's most lawless land.
R.J. Sloane captures the raw spirit of the American frontier in action-packed westerns that don't shy away from the harsh realities of territorial justice. Drawing inspiration from modern classics like Longmire, Yellowstone, and Murdoch Mysteries, R.J.'s stories blend historical authenticity with the timeless struggle between law and lawlessness.
A passionate student of Southwest history, R.J. spends countless hours researching the legendary lawmen of the region—from the Arizona Rangers to the territorial marshals who tamed pivotal frontier towns like Phoenix, Tombstone, Prescott, and beyond. Growing up watching John Wayne, James Garner, and Clint Eastwood westerns with dad on lazy Sunday afternoons instilled a deep appreciation for authentic frontier storytelling. This combination of classic western influence and dedicated historical research brings depth and authenticity to every story.
The Harper Justice series follows a family of territorial lawmen as they navigate the dangerous transition from frontier chaos to civilized order, where doing what's right often means defying what's legal.
