Grace Livingston Hill 
The Girl from Montana 

This is the story of a lovable girl upon whom fate has thrust a seemingly unbearable burden of trouble. She is alone in the mountains of Montana and threatened by a man whom she has every cause to hate and fear. Feeling that flight is the only course left, she arms herself, mounts a horse and bravely rides away. Thus begins a trail that finally leads her to the East, and to grandparents of widely divergent social stations. Her experiences with both are novel and sometimes humorous, but through them all she never quite forgets a certain tenderfoot who befriended her for a short time in her lonely journey. She meets him again under most unusual circumstances. Complications have arisen that threaten her future happiness, but in the end fate plays fair.
