Zane Grey 
Under the Tonto Rim [EPUB ebook] 

Over 30 million Zane Grey paperbacks sold since 1954. Lucy Watson has finally escaped from the town where she grew up. She takes a job as a state welfare worker and travels to distant Cedar Ridge to help „primitive” backwoods families improve their lives. She quickly overcomes their fears, and achieves popularity by the practical results of her work. From the grandeur of the old forests, loomed over by the immense Rim Rock, to the love of the children whose lives she can make more inviting, Lucy feels her soul expanding in its new setting. But amid the strapping hunters and uncouth drinkers, Lucy realizes that the life most likely to change is her own!
