About the Book
Book One in the Harper’s Justice Series. Where legends are made and justice rides hard.
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.
