This is a collection of short stories and novellas — but I skipped the first one, Souls, because I’ve read that one before. (Winner of the 1983 Hugo Award — it’s good, and I remember it well.)
Souls is, by far, the most straightforward story here. There’s a variety of approaches here, but Russ mostly enjoys befuddling people by having the text not actually explain what’s really going on. I quite enjoy being confused, so that’s fine by me. But I’m not surprised by responses like this:
