This was an interesting collection of stories. I had previously read some of Ted Chiang's writing that is available online and really liked some of it (The Merchant and the Alchemist's Gate and The Lifecycle of Software Objects in particular) and I loved the movie Arrival, so I was interested to read more of his work.
Pretty much all of the stories in this book are based on interesting concepts. I particularly liked Hell Is the Absence of God. I didn't really care for some of the other stories, but even the ones I didn't particularly like did have some interesting ideas and made me think. Overall, I'd say this collection is worth checking out if you're a science fiction fan.
