This was very uneven for me: I loved the concept of a planet that exploded but whose shards hung in orbit sort of together due to magic that gave each bit gravity, and each developed its own culture. It was the sort of educated space opera book that came from the 50-60s in influence--it cracked me up that in one page were three words I didn't know, whereas I did know many of the rather-pompous other words. That page escapes me now, but it cracked me up at the time.
The concept of 'the (sort of or presumed) dead who still walk' was a theme at the start and throughout, since this was a sequel to a big mess in the previous book which I have not read. One ninja-type guy escaped and pouted nobly since his mission had failed, and did all sorts of stuff to try to accomplish it, and there were other folks who were able to turn into animals, or who were assassins, or who were sorcerers of different types, walking-dead folks with mystical gothy illnesses, who all did their things and at times there was character development and pages dedicated to the inner world of a single character. Lots of that seemed to get wiped away though, so I found it ultimately disappoining, with a feels-like-a-cliffhanger ending, and am not tempted to keep the book. Early on I had thought it might be compelling enough to search out sequels, but I may have read it all in the single book, and that's enough for me. Some folks will love it, and some find it too pompously wordy or alien; it could even depend on the age of the reader and what that person grew up on.
