From national bestselling authors William W. Johnstone and J.A. Johnstone, a bold new saga of the American West centuries in the making, from the brave ranchers who staked their claims in the spring of 1842, to the lawmen who risked their lives to keep them, and the descendants who carried their dreams into the 21st century...

Bordered by the Blackfeet Reservation to the north and mountain ranges to the east and west, Cutthroat County is seven-hundred glorious square miles of Big Sky grandeur. For generations, the Maddox and Drew families have ruled the county--often at odds with each other. Today, Ashton Maddox runs the biggest Black Angus ranch in the country, while County Sheriff John T. Drew upholds the law like his forefathers did over a century ago. A lot has changed since the county was established in 1891. But some things feel straight out of the 1800s. Especially when cows start disappearing from the ranches. . .

Residents and news media still recall a gun-blazing tale of the land-grabbing battles fought by Maddox's and Drew's ancestors. Meanwhile, their present-day descendants face a new kind of war that's every bit as bloody. Sheriff Drew's girlfriend/deputy is shot and seriously wounded in what appears to be a routine traffic stop. When Ashton Maddox's rival rancher's foreman is found murdered and a modern-day vigilante group hires a hard-drinking, publicity-hungry retired Texas Ranger to investigate, Drew and Maddox decide to do what their forefathers did so many years ago: join forces against a common enemy. Risk their skins against all odds. And keep the dream of Montana alive for generations to come . . .
