Right now, one chapter in to Earth Abides, you have NO IDEA of the journey you are about to embark upon.
I ... no. I can't say that.
Well, there's this... nope. Can't say that either.
Just read it.
I'm about to read it again, just to take the journey again. I expect you will too, so putting off reading it just means you are gonna delay re-reading it even further! :-)
