Around 1900 Bower started to write about the wild west – and she was one of a few women writers that 'wrote like a man' and fooled most of her readers at the time. Not afraid to write about the violent times she is one of the best western writers ever, that this book is one of her finest of her character creations. 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, so they called him Nameless. A fantastic sequel to „Chip of the Flying U", „Dark Horse" is not to be missed by fans of Bower's wonderful work.
