The Prefect by Alastair Reynolds. Very well crafted. The usual good-guys-bad-guys shtick.
I enjoyed the prefect, it was good to see what the Glitter Band was like before the Melding plague. Reynolds does often have some quite good ideas, I like how many of his future societies have radically different forms of government than we do today. I often find it boring/unbelievable how many SF authors write about vast, futuristic interstellar societies and model their politics on US Federalism or the Roman Empire.
Yah, there is usually the presumption that interstellar trade is lucrative. I don't believe it.
Mr. Reynolds books are exceptionally well thought out, but there are still holes in the plot. I guess a seamless story is very difficult to do.
