Simple, stripped to the bare bones, this story of a man's effort to keep his son alive and to find any place of refuge in the wake of a great disaster is the finest achievement of McCarthy's career. I thought it was almost the perfect narrative — spare in its beauty and constantly driven forward by its own interior urgency. Impossible to put down, in other words.
I haven't read it, but The Road by Cormac McCarthy is getting rave reviews, not in the least from Stephen King. It's his top pick for best book of the year.
