This probably deserves a higher rating than I'm giving it: I read it in a single sitting, staying up far past my bedtime. It's quite the page-turner.
However, approximately nothing gets resolved. Two new plot threads are introduced, and only one gets to a reasonable stopping point. The other gets the equivalent of a season finale "to be continued..." Everything else is left just as in the middle of the action as it started, albeit advanced by 300 pages.
I'd put off getting this until the next one releases.
