As someone pointed out early on, but I've never really realised before, I don't think fiction is really for me. I have to say that at the moment, I'm torn between The Future of Geography, by Tim Marshall and Mark Kurlanksy's Cod.
NSC's at it's abstruse best
Get both. I haven't read "Future" but I have read Marshall's Prisoners of Geography.
The Cod book really is great though. Everyone I've recommended it to has enjoyed it.
