This is the second book I have read by Alastair Reynolds. I have the same impression of it that I had when I read "House of Suns".
Very well immagined. Anything he writes will be completely different from what you are used to. Also, the worlds are very rich and have a great deal of detail. Along the lines of "Ringworld".
The characters, there are 2 or 3 main characters who are not that engaging,and eveyone else is a "flat" plot device, and you never find anthing meaningful out about the secondary characters.
The ending does not tie anything up. It feels like it just stops, it was the same in House of Suns.
Rich text, deep characters, excellent writing... anything by Alastair Reynolds is worth your reading time... compares to "Perdido Street Station" by China Miéville, "Legend of Springheeled Jack" by Mark Hodder and "The Mad Ship" series by Robin Hobb.
Awesome world building, great story line, SteamPunk, excellent characters...
Interesting change of genre for AR. Took awhile to get used to, but came away with a good impression. Though he left a number of open plot lines in the book that could easily warrant a couple of more books.
