"The Sky Pilot" was written by Ralph Connor.
From the Preface:
The measure of a man's power to help his brother is the measure of the love in the heart of him and of the faith he has that at last the good will win. With this love that seeks not its own and this faith that grips the heart of things, he goes out to meet many fortunes, but not that of defeat.
This story is of the people of the Foothill Country; of those men of adventurous spirit, who left homes of comfort, often of luxury, because of the stirring in them to be and to do some worthy thing; and of those others who, outcast from their kind, sought to find in these valleys, remote and lonely, a spot where they could forget and be forgotten.
The waving skyline of the Foothills was the boundary of their lookout upon life. Here they dwelt safe from the scanning of the world, freed from all restraints of social law, denied the gentler influences of home and the sweet uplift of a good woman's face. What wonder if, with the new freedom beating in their hearts and ears, some rode fierce and hard the wild trail to the cut-bank of destruction !
The story is, too, of how a man with vision beyond the waving skyline came to them with firm purpose to play the brother's part, and by sheer love of them and by faith in them, win them to believe that life is priceless, and that it is good to be a man.
