The Road, by Cormac McCarthy, is, to say the least, bleak. The story of a man and his young son travelling the road south in a post-apocalyptic world. The son was born after the event that changed the world, but we don't know what that event was. And we don't know how so many people died, and why all the trees are burning, and why there are no animals around. It's a world covered in ash, where it's each man for himself, where your survival probably means somebody else will die. But the 2 keep going, in the hope that life might be better further south, by the sea (although there is no actual reason to believe it would be any different down there).
And yet, there is love, this amazing bond between father and son. They don't say much, but you know that they have gone through so much together, and that they need each other to keep going. Indeed, how would such a world be bearable if you were on your own?
I thought it was excellent. I was really moved by it.
And I would like to see the film, although some of the reviews are not so good
