Have you read his other works? Blood Meridian is great, though a little slower and more stylized. All the Pretty Horses is stunning.I just finished The Road yesterday, going to Barnes and Nobel after work to pick something up. Any suggestions on something similarly written?
As for other authors, Don Delillo is great, but can be a bit hit or miss-- White Noise is one of the greatest postmodern novels I have ever read. Libra is also fantastic, if you are interested in something a bit more complex (plot-wise) but written in a similar style.
If you are looking for more post-apocalyptia, I'd have to start talking about graphic novels and that sort of feels out of place in a thread about reading books
