B. M. Bower's novel "Rim o' the World" introduces readers to a rough-and-tumble group of range riders who scrape out a living in the foreboding and unwelcoming region known as Black Rim Country. Packed with suspense, action, and romance, this is a must-read for Western fans of all ages. B. M. (Bertha Muzzy) Bower was the first woman to make a career of writing popular westerns. And what a career it was -more than sixty novels published from 1904 to 1940, the year of her death, and still more posthumously. In the western orbit, Bower was - and still is - a star.
