So hey, got an advanced reader copy of CS: TAW at SDCC, and I've recently finished it (and mostly gotten over my post-flight migraines). So I figured I'd give you guys something of a review, sans significant details. (I'll at least try to talk in the general, but you should be warned that I can't promise that I won't let something slip. You have been warned.)
First off, the book starts off a tad slow, but starts to get you hooked about 4 chapters in. The problem is, this being a new series, it takes time for you to feel any emotional interest in what happens at first. Plus, this book doesn't jump you straight into the action, and begins a tad on the mundane side. Personally, I think the book might have benefited from picking another perspective as a starting point.
(Eg - He should have started with the cat, who is clearly the best character (and will tell you so repeatedly) & gone from there.
)
Still if you stick around long enough, the tedium quickly evaporates & you'll be committed to the long term.
Speaking of which, the general flow of the book is great. While the book is presented from a multi narrative perspective, you aren't left hanging waiting for each story to resolve. The narratives really flow well into each other, and there isn't a sense of individual story behind each chapter. (Oh, and it isn't in a journal style, so that helps.)
I won't say that I'm nearly invested into this series, as I am the Dresden Files, but I liked it significantly more than the Codex Alera books. I can't say that there isn't any minor quibbles or complaints I might have, but generally nothing worth mention.
The book did a fairly decent job of presenting a interesting new world & a story to go along with it. If you are willing to give it a chance, I think you'll be pleased with your reading.
