B. M. Bower 
The Lure of the Dim Trails [PDF ebook] 

This is an interesting twist on a Western, where an author returns to the land where he was born to get some ’local flavor’ for his novels. He gets much more than he expected, going on long trail rides and nearly freezing the end of his nose off in the winter shacks. Something—it couldn’t possibly be the beautiful Mona—could it?—keeps him on the range all year.
And of course there is a young woman to fall in love with, Mona of the gray eyes. Will she ever see him as anything but an Eastern dude? How can he show her that he has just as much courage as she does?
