There are a couple of interesting features of this story that I would like to discuss - but I don't want to introduce any spoilers, so I'll just leave this here for now.
I quite like Chiang myself. There is a quality to a few authors like him, Mieville, and Egan that I can't figure out what it is but really like. Possibly linguistics, good worldbuilding, and rarely having their characters be inexplicable idiots.
