This is B. M. Bower’s 1931 novel, ‘Dark Horse – A Story of the Flying U’. Big Medicine was a hero among the cowhands of the Flying U after he saved the stranger on horseback who had been struck by lightning. However, their mysterious guest seemed to have amnesia and couldn’t remember who he was. A fantastic sequel to ‘Chip of the Flying U’, ‘Dark Horse’ is not to be missed by fans of Bower’s wonderful work. Bertha Muzzy Sinclair or Sinclair-Cowan (1871 – 1940), more commonly known as B. M. Bower, was an American author famous for her novels, short stories, and screenplays set in the American Old West. Other notable works by this author include: ‘Casey Ryan’, (1921), ‘The Long Loop’ (1931), and ‘Chip of the Flying U’ (1906). Many vintage books such as this are becoming increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with a specially commissioned new introduction and biography of the author.
