I have admired Louis L'Amour for years. I strongly suggest you read his auto biography Education of a Wandering Man. I have so many favorite L'Amour stories its hard to limit them to a couple.
The Iron Marshall- Excellent western murder mystery
Bendigo Shafter- Just a big historical read, greatr fun.
Comstock Load- Good history and a fine education in geology
The Sackett stories- Rollicking is the best way to describe them
All his books are mental popcorn and I reread them quite often.
