Blood Meridian (or The Evening Redness in the West) by Cormac McCarthy. Quickly became my favorite book after reading it a second time. I've never read a book with more effective language.
I read The Road, and it was so sufficiently “effective” in its descriptions and it’s setting that I’m happy never reading another McCarthy book again. Glad I did once.
I will watch the movies though!
I went out and bought The Road but for some reason or another haven't yet started it (have watched the film though).
