Not quite as good as the first two in this series. I'm sure fans will still love it, but I found it a bit tedious.
It's quite long - 540 pages, and the great majority of that involves the characters sitting around during pointless political negotiations that seem to be going nowhere. (the kingdom of Skala, at war with neighboring Plenimar, needs access to the forbidden land of the Aurenen - specifically, their ports - in order to gain a military advantage.)
Finally, things pick up when some people start getting killed - but then it falls into typical murder-mystery tropes, and Seregil starts acting more like Sherlock Holmes than one would expect.
I'm not ruling out reading more of this series at some point in the future, but I feel like three books is enough for me, for the time being.
