The prolific authors, husband & wife, have 100+ books to their credit. Many of those books are westerns, and this is the first of a series of 7. Comparisons to the late great Louis Lamour are rampant. There's a protagonist who's fought for the losing side in the Civil War, now he's driving a herd of Texas longhorns in the still nearly pristine Montana Territory. He stops in a fledgling town along the railroad line that ultimately will unite the country, and does a good deed by breaking up a fight that was turning ugly. He gets propositioned with a job offer, since the town needs a marshall. Somewhat predictable events transpire. Lots of western language that you try to assume real characters actually used. This is an easy read, quite enjoyable if you like the genre. Lack of finality in the last chapters is the clue that the hero will appear in more adventures.
