I wasn't supremely overwhelmed
I mean, don't get me wrong, the book was a good read.
But I was sort of expecting Harry to dish off against a multitude of "ghosts". Not just the wraiths and the lemurs, but maybe to square off against past villains. It would have been neat to see Harry's current magical talent face off against previous foes.

I got the feeling that the whole Fitz and Aristedes debacle was just created to fill up the Book. If Jim would have substituted that area of the book and replaced it with visiting Ebenezar, Luccio, Michael (hell, maybe even Charity ) and other key characters. It would have gave me better satisfaction.

But Hey, Jim has said that he has outlined the books, maybe Fitz will prove a bigger ally down the road.
