Safari ate my long ass review so here are some brief thoughts while I compose myself.
Reynolds is great at the ideas but not as great at characters.
I have never read a Reynolds book that I regretted reading.
In the Revelation Space series, this is far better than Revelation Space but not nearly as good as the excellent Chasm City.
I am looking forward to reading the last in this series (other than perhaps The Prefect, I'm not sure about that one),I am looking forward to it even though I know full well that Reynolds is incapable of ending a story in a satisfying manner.
The Revelation Space universe is probably my favorite SF universe.
I might come back and fix this with an actual review at some point but my history suggests I will just intend to for a long time and then move on.
