First of all, I'd like to say Michelle Sagara even on a bad day is still so much better than 99% of the fantasy stuff out there that I'll give her a pass on this one. I'll still continue to follow the series and eagerly snap up the "Cast in..." books as they appear. But this one just came across as a lot of random and repetitive "sound and fury, signifying nothing." Sagara seems to have fallen in a rut: "when I don't know how to resolve matters, I'll throw in ten more characters and just complicate matters." (Somewhat along E.E."Doc" Smith's habit of throwing in a new set of aliens or another piece of monkey-wrench technology when he needed to jazz things up.)
Certain hanging problems from the multi-book plot seem to have been resolved--although Sagara also added several more, so I don't think we've got that much further towards resolving dangling issues. I thought that Sagara had a plot line in mind for the entire series, but unless she plans to try to stretch this series out until doomsday, shouldn't we be seeing some movement towards the final conclusion? And shouldn't we by this point have some idea what the final conflict will be about?
On the writing style: As others have commented, too wordy and repetitive. Sagara has the makings of a fine book here (and there were lines which caused me to laugh out aloud with Sagara's wit), but this book should have been much more tightly edited.
