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 U.S. 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—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 . . .
 
“McCauley’s more than a fair hand at Westerns . . . with  nonstop action.”
—Roundup Magazine on Where the Bullets Fly

—True West

“A captivating western . . . the setting is harsh and even the violence is gratifying.”
—Booklist, STARRED review on Dark Territory Praise for the Sheriff Aaron Mackey Westerns
 
 “A captivating Western…the setting is harsh and evocative; the villain is sufficiently slimy and scheming; and even the violence is gratifying, as the punches are strong and swift and the bullets whiz by close enough to make readers' hair stand on end. The plot progresses with calculated, yet dramatic, twists and turns…The author manages to craft an ending that will strike the reader's sweet spot between being deeply satisfied and yearning for more. Folks picking up this title will likely seek out the preceding book and will eagerly wait for the next.” 
—Booklist, STARRED Review on Dark Territory
 
 "Comes out guns blazing from the very first page and doesn't let up until the action-packed finale...McCauley does an expert job of weaving suspense and intrigue into this traditional Western tale. Along with the enjoyable Western tropes, McCauley incorporates elements of a good old-fashioned mystery that make this book a real page-turner." 
—True West on Dark Territory
 
“Dark Territory has much to offer. Well written, it is at once a first-rate Western, expertly exploiting all the genre’s tropes and traditions, and a political thriller, as Mackey needs to rely on his acumen as much as his brawn and shooting skills. Well-paced, its quieter moments are as compelling as its outstanding action set pieces. McCauley has definitely piqued my interest—I’m going to seek out previous works, as well as follow him in the future.” 
—Mystery Scene
 
 “Sheriff Mackey is a hard-nosed Western hero of the Civil War who packs a punch with both his fists and his guns. Prepare yourself for a fast-paced ride as you turn the pages as tension builds until the final chapter”
—The Historical Novels Review on Dark Territory
 
 “Terrance McCauley has done it again. The author of Where The Bullets Fly has followed it up with another excellent read, Dark Territory…Train robberies, labor agitators, small town elections, suicides, love interests, attempted assassinations, and shoot ‘em ups fill the book. The action starts on the first page and keeps on going. Twists and turns kept me from figuring out the ending until I had only 2 1/2 pages left to read. Enough, I don’t want this review to be as long as the book. Get it, read it, you will be glad you did.”
—Rope Burns on Dark Territory
 
“The action starts in chapter one and doesn’t let up.” 
—Rope Burns
 
“Sheriff Mackey is clearly defined, realistic for the time period, and totally believable. The pace, from the opening pages to the final satisfying end, is unrelenting. An exceptional Western novel.”
—Historical Novels Review on Where the Bullets Fly
 
“Fans of crime fiction and thrillers know Terrence McCauley as a first-rate storyteller who can handle action scenes while capturing the mood of New York City in the 1930s and today. Turns out, McCauley’s more than a fair hand at Westerns too…Imagine a spaghetti Western with flawed characters and nonstop action. Or Rooster Cogburn, without the eyepatch and a whole lot meaner.”
