Dover Station, Montana, is no place for a lawman. A sheriff's badge ain't worth a nickel here—unless you've got the bullets to back it up . . .



When he signed up to be sheriff of this dirty little boomtown, Aaron Mackey knew he was asking for trouble. Once, when Mackey was the US marshal for the whole Montana Territory, he swore no job could get any harder. But that was before he took down a few of the bank-robbing Hancock gang in Dover Station—and incurred the wrath of the gang's maniacal matriarch, Mad Nellie Hancock.



And that was before every avenging outlaw and hired henchmen came crawling out of the woodwork to kill him—in the meanest, bloodiest showdown the town had ever seen . . .



Aaron Mackey knows you can't fight city hall. But you can flush out every kill-crazy outlaw, greedy grifter, and boomtown rat—then exterminate with extreme prejudice . . .
