B.M. Bower 
Her Prairie Knight [EPUB ebook] 

Eastern society girl Beatrice Lansell, on a visit to her brother’s Montana ranch, is being pressured by her social-climbing mother to accept her English nobleman suitor, Sir Redmond Hayes. She fills her days with coquetry, leisure and meaningless flirtations, but she has never found true love. The staunchly independent Beatrice finds herself equally annoyed and attracted by mysterious cowboy Keith Cameron. Will this improbable romance last? There’s plenty of conflict as corporations start buying up the free range, plenty of excitement and danger from the elements and criminals, and of course, plenty of romance as a New York socialite and a ruggedly noble cowpuncher fall in love.
