B. M. Bower was the first woman to make a career of writing popular westerns. Her works, featuring cowboys and cows of the Flying U Ranch in Montana, reflected âan interest in ranch life, the use of working cowboys as main characters, 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. âThe Parowan Bonanzaâ is one of her stories. This short but engaging novel contains all of the elements that made B. M. Bowerâs books a mainstay of the genre of classic Westerns.
