I finished The Caryatids by Bruce Sterling over the weekend.

The Caryatids is set in an environmental dystopia where global warming has damaged the Earth badly enough to de-stabilize most of the world's nation states. The titular characters are a group of highly dysfunctional clones that become central to global events. The four surviving ones (of a set of seven) all hate each other, and their "mother", and refuse to interact, meet or even talk about each other.

The story was interesting, even though most of the characters are fairly unpleasant, and emotionally over-wrought to the point of annoyance. Sterling's thoughts on the environmental dangers of global warming seem over-blown, given current projections, and his political and economic ideas seem crank-ish, and that's probably being generous.
