Blood Meridian is tough going. The violence in that book is mind boggling. I really enjoyed Sutree.
No doubt on Blood Meridian. It was the first McCarthy book I read, though, so it stands out to me. Read it on the beach in Hilton Head one summer. Light summer fare. Sutree is good. I also enjoyed the Orchard Keeper, but for the life of me I can't recall the narrative. I'll have to go back and re-read it.
Like Jeff said, don't expect happy endings.
I will look for Craig Childs. I've got stack I'm working through right now. Peter Matheissen, Gabriel Garcia Marquez, and some Henning Mankell. I only get to read for a bit after the kids go to bed, so it's slow going.
