B. M. Bower 
Good Indian 

Good Indian is a foster son of a western ranch owner. Considered as the eldest son, Good Indian plays a pivot role when the family ranch is attacked by scheming, gold prospectors. He is taken by the beauty of one fragile girl who cannot understand the western customs. His partner and supporter, Georgie Howard, quells her love for him, when they both go through the legal battle of the family ranch. Bower gives the reader an excellent portrayal of a man loved by more than one woman.(Goodreads)
