"Hell Is the Absence of God" has stuck with me since I first read it in a collection almost 20 years ago, and Arrival was an instant favourite film when it came out, but somehow it has taken me until the past few years to read more of Chiang's work. I'm glad that I did. Exhalation was brilliant, but I think this collection tops it—the combination of religious/mythical thinking and the methodical, engineering mindset gives each story a unique blend of rigor and depth. He makes worlds where impossible things happen but feel entirely believable, and tells stories that are laden with metaphor and commentary that don't feel didactic. They're magical and often beautiful, but never fanciful—which I mean as high praise.
