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'll have to reread before I can make a comment specific to this story. But I found the collection as a whole (Stories of Your Life and Others) incredibly stimulating. I don't think I've ever seen so many really original ideas between two covers.
Man, the Babylon story and the Arab world story were both incredible. Excellent worldbuilding passing off complex ideas and making them Buffy-spoken in terms of understandability, with scattered crunchy genius bonuses.
