As ever with fantasy trilogies, everything I said true of both the first and the second
pretty much holds true for this. And now that the actual conclusion is hoving over the horizon, it doesn't have the problem a lot of second books do in feeling like filler. Basically I think if you've got to this point in reading a trilogy you're already submitted to the world and the characters and the general approach that ... unless something really grotesque happens ... you'll like how it ends.
I liked how this ends.
It's a bit AH D'Y SEE but I guess we were pretty blatantly heading there all along.
