There’s a lot to like about this book. The narrator (both in an audiobook and a diegetic sense, though I think the former certainly accentuated the latter) is terrific; the Borgesian framing and setting (and central mystery) is really fun and interesting; it is extremely well-paced and padded so that it never outstays its welcome. I found myself weirdly disappointed with only two things: the “twist”, if you could call it that, is pretty immediately obvious (gee, I wonder what a “shining rectangle” could be!) and the denouement/climax felt extremely pre-ordained: not a single scrap of the final 20% of the book was surprising or interesting, even if I thoroughly enjoyed how you get there.
But what is a few days of feeling cold compared to a new albatross in the World?
