1915. With frontispiece by Douglas Duer, Bower authored several Westerns including Cabin Fever and The Flying U Ranch. This book begins: Without going into a deep, psychological discussion of the elements in men's souls that breed events, we may say with truth that the Lazy A ranch was as other ranches in the smooth tenor of its life until one day in June, when the finger of fate wrote bold and black across the face of it the word that blotted out prosperity, content, war family ties, -all those things that go to make life worth while.

Bertha Muzzy Sinclair(November 15, 1871 – July 23, 1940), best known by her pseudonym B. M. Bower, was an American author who wrote novels, fictional short stories, and screenplays about the American Old West.Her works, featuring cowboys and cows of the Flying U Ranch in Montana, reflected "an interest in ranch life, the use of working cowboys as main characters (even in romantic plots), the occasional appearance of eastern types for the sake of contrast, a sense of western geography as simultaneously harsh and grand, and a good deal of factual attention to such matters as cattle branding and bronc busting."
