This was a surprisingly moving story of love and death, set in the future, in a world after “the singularity” - the point at which artificial intelligence and human intelligence become effectively the same thing. It’s a very short book at around 7500 words, but manages to pack in a lot of story. I bought it when it was available for free as a promotion for the rest of the series.
The tale is told from the viewpoint of a medical robot whose job is to “restore”, i.e. to heal, “legacy humans”, the ones with old-fashioned human bodies which need medical care rather than the ones who have “ascended” to life as a machine. As the story progresses we track the robot’s happiness level. Expressed as a number from 0 to (presumably) 9 or 10 this is a really neat way of indicating a kind of emotional state for a machine which does not, as such, have one. Happiness is increased by being needed, making humans happy, and successfully restoring humans to better health. Happiness is reduced, it turns out, by confusion, lying, failure, and rain.
The story represents a snapshot of one case where the robot is required by an ascended human to help with the care of his legacy human artist in residence. It is clear that they care deeply for each other, despite the social stigma of such a relationship, and he is willing to do whatever he can to save her. His methods are unorthodox, and cause problems for the medical robot.
For such a short story this was intense, enjoyable, and surprisingly believable. I was immersed in the story and its world from the very start, and found the tracking of happiness level to be a masterstroke in giving life to a machine character. Even the otherwise cliched use of rain to signify death was cleverly explained and used as part of the story.
I can’t imagine that further stories in this series will use the same point-of-view character, so my best guess would be that the rest will be other stories from other characters but set in the same post-singularity world. I’ll keep an eye out for them.
