The Road by Cormac McCarthy
The premise is simple: A young boy and his father trek across a post-apocalyptic landscape, surviving day to day in an inhospitable environment. It's a plain story told plainly yet I found myself rooting for these two lost souls. Actually, not much happens in the story. It's actually pretty cliche. They journey, they find food, they run out of food, all seems hopeless, they find food again, etc. And yet, I kept with it. I was compelled to see if things would turn out alright for the man and the boy. Do they? You'll have to read it yourself to see.
