His book “The Road” is on the Oprah’s Book Club List so that means more of the general public will read that book and then usually that leads them to check out his other books. So he’s going to do just fine now that Oprah has said it’s a good read.
There’s another real issue that is problematic and that is reading uses a different part of the brain than watching tv or a movie. The written word stimulates linear reasoning on the left side of the brain, images are processed on the right side of the brain- the feeling side.
The Road really isn’t his best effort. I suspect the majority of folks who read it won’t finish it. It’s somewhat brutal. What was Oprah thinking? As for money, he’s doing just fine since they made All The Pretty Horses into a movie and optioned all the other books.
