This is one of those very rare books that reminds me of what books are at some level all about. That makes me want to go about and knock about two stars off of 99% of my prior book ratings, to make room to properly differentiate this one.

It's hard to say too much that's concrete, without giving it away. I was closer to tears at the end of this than I can remember with any book for a long time. Not easy maudlin tears, but deep oh-my-god tears about what a universe this is.

The people are very fully people; the viewpoint character is not a person, but ... well, that would be a spoiler also. But the viewpoint it gives her allows Ishiguro to say some amazing and touching and true and thought-provoking things without coming out and saying them (because nothing he could come out and say would say them so well).

Language cannot express truth, I often say; but what I mean is that it can't explicitly express literal truth. Language, when it's used with this much expertise, can and does express deep and breathtaking truth.

I need to go spend a few weeks processing this now, I think..

If you haven't read it yet, I highly recommend that you should,
