City by Clifford D. Simak. Quite a pessimistic view of mankind as seen from the '40s. It's a bit dated in some respects, but on the whole it's a pretty interesting read.
Was wondering what you thought about it, Ben. A Hobbit favourite, reviewed HERE btw.

To my younger self, City was a bit of a puzzle on first reading. So I read it again. And have a few times since. These days, thirty-odd years on, City is one of my Simak favourites: more than that, it is one of my all-time favourites. And yet I still really don’t know why....
It has dated (and towards the end, horribly) but there are parts I love. Dogs and robots left in stewardship of the Earth? Humans abandoning the Earth?
