I just finished the 2 books. The first was dragged out with more cliches than I have ever read in one book. He even starts out the book with the oldest one from the original western novel, The Virginian,
"When you call me that, SMILE!"
I have a copy of the 2nd printing of that book from 1902.
The second shorter book, however, is about how the "Preacher" ran away from home at age 12 and his adventures into manhood. It is very good.
If all of the author's books were as good as the second one in this double volume, I would buy them all.
By the way, the original rendition of "The Virginian" is good but because it is written in Victorian-style English, it's a bit difficult to get into the swing of things until you get used to the style of writing. After you do, it's quite enjoyable and not a bit like the TV series was.
