This was a re-read for me - but it's been over 20 years since I first read it. It's interesting to come back to something after so long. I'm happy that I still really, really liked it.
It's a reading experience that's more like experiencing a poem or a song than a typical novel. This is not to say that the plot is not clear and easy to follow (if anything, the plot might be overly simple, given such a rich and complex universe), but it is suffused with almost a synaesthesia of the senses, with music and glittering darkness. It's full of weird and wonderful imagery.
That said, perhaps some people might find it dated in some ways - personally, I found it giving me a nostalgia for the time period when it was written, which was much more filled with over-the-top fantasy, with an unabashed flair for the dramatic. Although this is sci-fi, it reminded me of when goth was all about beauty, decadence and playing at cruelty and power, skirting the edges of convention. Some people found goth rock too bombastic too. I don't.
I wish Somtow would write more SF. Being a conductor is all very nice and worthwhile, but.... More Books! :-)"
