Alright, I want to try to catch up a little bit this year, including posting my review of this book that I read...um....two years ago. Don't expect regular posts or anything, but I do want to keep my streaks in the Hugo, Nebula, and Locus SF novel awards going.
So, 2312 is pretty typical work from Kim Stanley Robinson, who is a favorite of mine. There's very strong world-building, as we once again get the Accelerando and its colonized solar system with lots of inventive terraforming (see Galileo's Dream and Blue Mars for other examples). There are some interesting ideas about social and political developments, clearly based on Robinson's clear understanding of history and social science. And your mileage with plot and character and prose may vary.
I found this novel especially uneven on the latter three counts. Robinson is a hard sf writer who really seems to put some energy into his style, and here he tries a little experimentation. It's appreciated but not entirely successful, and it stands out awkwardly next to some rather lengthy passages of technical writing focusing on the aforementioned world-building. Similarly, the characters can feel a little flat. Robinson's usual trick is to give his characters universal traits like love and ambition while also placing them in very specific historical and cultural contexts, and I think he's generally better at the latter than most of his peers. Here, the characters have immense longevity and the ability to change aspects of their appearance and identity fairly freely. At times, this is all realized wonderfully, and the best portion of the novel involves a gender fluid romantic arc with the main character Swan. Often, however, the characters just feel distant and cold - there's a lot of telling but not much showing, for instance, about how much Swan was inspired by a deceased character named Alex, whose death drives much of the plot.
Speaking of the plot, this is where the novel fails to realize its potential. It's basically a mystery, as Swan wanders the solar system investigating a series of dramatic terrorist attacks, but the investigations mostly feel engineered to show off the various exotic settlements, including a massive train city that circles Mercury between its light and dark sides - a device Robinson has used before, but he really goes into depth here. The setting is driving the story, not the characters.
2312 was more ambitious and literary than most of its competitors in 2012 (what I would have called a very off year, looking at the nominees), and I liked it quite a bit, but its flaws are evident enough that I'm not particularly bothered that it got beat by the fairly silly Redshirts for the Hugo and Locus.
