As they make their way across the country, they encounter bizarre and terrible things, the more bizarre the farther they travel, and the companions begin to lose something of their own humanity until at the end . . . . Nope, not going to tell you. Wouldn't be prudent. Anyway, I think most of you will have a pretty good idea well before you get to that part. And that's the weakness in the book. I knew well before the end where it was going. Getting there, however, was worth the trip. There's some heavy-duty violence, but the setting and the characters and the quality of the writing are all topnotch.
