Slightly off-topic, but I'd definitely recommend Colson Whitehead's _The Intuitionist_[1] for anyone interested in the intersection of elevators and speculative mysteries. Never thought I'd get the chance to post this to an HN thread...
One of my first thoughts too. I preferred John Henry Days, but whatever. As for The Intuitionist -- the whole thing is kind of a troll. Like, the premise is absurd. Of course, that's sort of the point.
It’s really nice to get some fiction recommendations from HN! Looking forward to reading this
