I'm currently reading 'Cities in Flight' by James Blish. It was written in the 70's and, like many books of its time, foresaw extended tensions between Russia and the West. However, despite the fact that the 'enemy' has now shifted, Blish still realised how extended 'wars' would lead to sides throwing away some of the fredoms and ideals they supposedly fought for for reasons of 'security.' (Of course, Orwell saw the same thing, although in his case the war was suggested to be largely artificial, invented to allow control of the population.) Oh, the book itself is fairly heavy going at first, and takes a while to heat up. The first part is initially rather fractionated and can be a bit confusing, as it is a while before any cohesive narative forms. It gets slightly more structure to it later but in my mind fails to achieve anything truely novel. However I'm just over a third the way through it, so it still has time to impress.
