recently finished:
1985 by Anthony Burgess
Top notch. A sort of weird critique of 1984, including imaginary dialectics, followed by a slim novella re-imagining it from the 70s. The best explanation i've seen of why Thatcher was popular.
The Business by Iain Banks
Meh. Well written, well imagined premise and some great set pieces. Not enough plot for a thriller and not enough character to be anything else.
