Also, about 75% through The Dispossessed by Ursula K. LeGuin after a short hiatus due to being fucking exhausted from working non-stop and living in two weeks of non-stop 90 degree heat and humidity. It's really fantastic.
The Dispossessed is an excellent book. It's a shame is isn't better known among the SciFi canon. I suppose it doesn't lend itself as well to simple analogies like 1984 and Brave New World, so it has fewer acolytes.
