It's not often that I re-read a book that, while I enjoyed it, I had a struggle doing so. However, several of Joan Slonczewski's fans, one of whom I trust quite a bit, encouraged me to re-read her book
Brain Plague.
The basic plot is straightforward: a middle-tier artist who has moved to her interstellar empire's capital world to be part of the art scene is accepted for an "experimental" medical procedure that, she is told, will boost her intellectual capabilities. While this is going on, a "brain plague" is moving through the population at large, a blood-borne disease that turns people into zombies who either die or mysteriously disappear. Our heroine discovers that what she is getting is, in fact, a colony of millions of sentient beings who live at speeds hundreds of times faster than she does, and their 'boost' is in fact her leeching off of their creative efforts. They don't mind, though: they can only live within a human host and she, in effect, becomes their "god," and all they do is for her well-being. The plague, it turns out, is made up of corrupt colonies of these beings who take control of their hosts pleasure centers, addicting their hosts and sending them on an involuntary religious quest to find "the Eternal Light."
From here, much personal and political hijinks
( The original review )I was hoping, upon re-reading, to discover that I had read the story incorrectly. I had not. Instead, I found the story even more bizarre. The characters flit from starsystem to starsystem in starships as casually as you and I take a subway. Sentient AIs have a scatological problem: mentioning "waste heat" is even more offensive to them than any epithet human beings use among themselves. Despite the enormous variance among the AI characters, they're all trying to found a city on a planet for AIs only just to show the protein machines that they can. There is no investment scheme targeting poor villagers living on the backward from which heroine Chrys comes, exploring the economic value of an entire planet that it's quite cheap to exploit, no capitalist at work trying to make the universe more productive. The economy, the social structure, the moral milieu, everything about this universe exists only by authorial fiat.
There is a class of writer that does not understand how the world came to be the way it is. She looks around and see class divisions and economic segmentation and doesn't understand why those institutions exist-- and then she extrapolates, badly, from the existing to an analogous SFnal setting. Slonczewski has done that with
Brain Plague, but in the process she has given her class segments and economic segments (or their progenitors) capabilities that should destroy and re-arrange the distinctions with which she's trying to analogize.
Slonczewski remains a great writer of characters and their relationships (except when she doesn't; she does a poor job of communication Chrys's social life, using it primarily as an excuse to drive her into the grubbier bars), but she introduces ideas willy-nilly into her story without really grasping the consequences of her actions.
