Unlike many others I actually liked book 10 quite a bit. Yes, I agree that not a lot actually happened if you were looking for resolution to any plotlines, but it did set up almost every one of the plotlines on the edge where you knew in the next book there would be a lot of action taking place in the various story arcs. In that regard I think that book 10 worked very well. That is just my opinion though.
