As I walked towards it, I noticed it was some kind of refill station. Cars were parked there, under a horizontal canopy and stationed next to simple-looking fuel-delivery systems. It was confirmed: the cars did absolutely nothing for themselves. They were practically brain dead, if they even had brains.A novel about an alien who is sent to contemporary Cambridge to wipe out all knowledge of a particular mathematical theorem, and observes the weirdnesses of human society from the viewpoint of an outsider. It didn't really work for me; I found the protagonist a bit too detached, and the afterword to the book which makes clear that it's all Really A Metaphor rather retrospectively spoiled the reading experience for me. Lots of other people seem to have loved the book, but I didn't. (Read in January, only getting around to blogging now.)
This was the most popular book on my unread shelf acquired in 2015. Next up is Etymologican, by Mark Forsyth.
