Well my favorite Louie Lamour book is his early one which was made into john Wayne movie! Hondo!
Do you know Robert B. Parker's book Appaloosa? It's good.
Also a good film:
I read the book many years ago, and didn't like it, but maybe the movie is better.
The Louie Lamour books annoyed me, the way he had his characters hyper-explaining historical details at every chance, like no normal person would, but I do love the movie "Hondo."
