McCarthy's novel "Blood Meridian" [1] is one of my all time favorite novels and continues to be a source of inspiration. Its almost biblical in its prose and unrelating in its pace and violence. I even wrote a song based off it (shameless plug) [2]. The villain of the story, Judge Holden is up there with the Joker for me in sheer evil. I would love to see a movie adaptation of it although I doubt it will ever happen. Too bloody. Too violent. I highly recommend it if you aren't easily put off by its dark tone.
