Bertha Muzzy Sinclair or Sinclair-Cowan, née Muzzy (November 15, 1871 – July 23, 1940), better known by her pseudonym B. M. Bower, was a prolific American author who primarily wrote Western stories, bringing to life the adventure and mystique of the American frontier. Bower was one of the first female writers to make a substantial impact on the Western genre, a field dominated by male storytellers at the time. She was not simply a writer but a pioneer who carved a place for women's perspectives within the genre. Her narratives often featured strong, capable women alongside cowboy heroes, reflecting her own independent spirit and progressive views. Bower penned more than 30 novels and numerous short stories during her career, with one of her notable works being 'Skyrider' (1918), which presents an engaging tale of aerial adventure and frontier life. Her literary style blended authenticity with romance, capturing the rugged realities of ranch life while also spinning yarns with emotional depth and compelling plot lines. Unafraid to address the hardships and lawlessness of the Western frontier, Bower's work remains a testament to her storytelling prowess and her substantial contribution to popularizing the Western genre among a broad readership. Her characters are not mere stereotypes but fleshed-out individuals, reflective of Bower's keen observation and understanding of human nature.
