I grow tired of lists of the same old "classics," even though I love most of them, so, here are a few others that might not be included very often:

The Voice of Bugle Ann - McKinley Cantor

The Cossack and the Cowboy Cowboy and the Cossack (Thanks, Wesley. You're right!)

Louis L'Amour's Walking Drum

Anything of Badger Clark's

Letters of a Woman Homesteader by Elinore Pruitt Stewart

My Friend Flicka, Thunderhead, & Green Grass of Wyoming - Mary O'Hara
