Stars in my Pocket Like Grains of Sand by Samuel R. Delany
I have a suspicion that I am not quite smart enough to read this book. I have a strong feeling that there was Something Important and Deep going on that I didn't quite pick out. I liked the setting, and the characters, but I kept expecting the story to have bigger events, questions answered, etc. I'm guessing that there are important reasons why the story was shaped as it was, but I'd have to re-read it a few times to work it all out. The story ends in misery, which I appreciated. This was the third "fluff" book in the current cycle, though it ended up being heavier than a lot of my "serious" books.
