Despite an early chapter’s reference to a possibly-autistic character’s “oblivious grotesqueries”, I’ve decided not to drop Last Day and just do my best to solider through until the end. Sarah Moss, it turns out, is not the only character with some fairly ugly observations of that kind, and the entire International Space Station thread strains credulity, but since it’s moving relatively quickly I’m going to err on the side of not already leaving another book unfinished.
Although I am impatient to move on to The Black God’s Drums by P. Djèlí Clark, which I have waiting in the wings.
