Our friend Offline Chuck has read a couple of those novels too and could give you a second opinion. I was at the book fair last weekend (tickets courtesy of OCD) and I saw two of C. J. Box's novels. Only trouble was, one was $30 and the other was $80. They must have been signed first editions! I opted for a book of stories and illustrations by Charles Russell, the artist, that was only $12. The seller told me that the stories are very colorful and interesting. I remember Annie Proulx mentioning his work too. He, Remington, Bierstadt and Owen Wister pretty much put Wyoming and the West on the map for curious Easterners.
