Apart from the terrible decorative typeface used for the first few words of each section, thus making the book appear to start with the words "The clay war was declared, ...", it's vintage Stross, with an idea density greater than anyone else except for Greg Egan. No spoilers yet (I don't really think that revealing the first five words can count as a spoiler), especially as I'm only about sixty pages in to it. But not since the Forge Of Goo incident have I seen such a naff typeface on an SF book.
And it takes my mind of the heat. My flat faces east and the long external wall is all glass from about three feet off the ground to eight feet off the ground. Even with the blinds closed, the internal temperature goes extremely high on sunny mornings.
