That is pretty much my feelings on Dzur, yeah. I read it before/after surgery, and so I always think my memory of it is just blurred by stress and anesthesia recovery, and then I go back and flip through it and . . . yeah, not much happened. (But it does make a good unchallenging surgery recovery book!)

I keep wanting to find a way to appreciate Jhegaala and failing. Moving on to Iorich seems like a good choice. I will strongly suggest going back and reading the Khaavren novels before you get to Tiassa, though, if that hasn't been suggested yet--at very least The Phoenix Guard and quite possibly all of them.
