Zane Grey 
Riders of the Purple Sage [EPUB ebook] 

A sharp clip-crop of iron-shod hoofs deadened and died away, and clouds of yellow dust drifted from under the cottonwoods out over the sage.
Jane Withersteen gazed down the wide purple slope with dreamy and troubled eyes. A rider had just left her and it was his message that held her thoughtful and almost sad, awaiting the churchmen who were coming to resent and attack her right to befriend a Gentile.
She wondered if the unrest and strife that had lately come to the little village of Cottonwoods was to involve her. And then she sighed, remembering that her father had founded this remotest border settlement of southern Utah and that he had left it to her. She owned all the ground and many of the cottages. Withersteen House was hers, and the great ranch, with its thousands of cattle, and the swiftest horses of the sage. To her belonged Amber Spring, the water which gave verdure and beauty to the village and made living possible on that wild purple upland waste. She could not escape being involved by whatever befell Cottonwoods.
