What a great idea, HomeInMyShoes. I haven't had an excuse to read a western, it might be fun. I'll second The Virginian, and here's a couple of links that actually work for it: ePub Mobi

But you've inspired me, and I'm also going to nominate the absolute classic of the genre: Zane Grey's very first Western: Riders of the Purple Sage.
Dr. Drib's Description:

Spoiler:

"Riders of the Purple Sage, published in 1912, was Zane Grey's first best-selling novel of the many he was eventually to pen. It has never been out of print, is a solid entry in the canon of American literature and is considered one of the best Westerns ever written, if not the best of them all."

There's only an LRF version up in the PCML, but I'm sure we can all manage to convert with Calibre, or one of us can upload a couple of conversions. I've never read this, and yet it's perhaps the best known and most read of the entire genre. Should be fun!
