I just started All the Pretty Horses by Cormac McCarthy.
It's been sitting on my shelf for months along with Cities of the Plain. My girlfriend bought me The Crossing for my birthday, so now that I've got the trilogy I figured it would be a good time to start :)
Enjoying it so far. It doesn't seem nearly dark and calamitous enough yet to be a Cormac McCarthy book, so I'm constantly bracing myself waiting for something tragic to happen... Which I'm sure it will eventually.
EDIT: Yep, I spoke too soon. Damnit.
