The Stone Canal by Ken MacLeod

I remember this being the most confusing of the Fall Revolution novels, and it still is on re-reading. It is packed with more ideas than the others, and none seem quite as completely explicated. Still, it's interesting to see the story of a couple of characters you met once each in The Star Fraction played out in full over the course of a couple of hundred years here (this pattern continues in the other books, each is a story that is tangential to that first novel).

Still, there's plenty here to like, and the ideas are fascinating to think about, even if I would have liked to have them developed further in the novel.
