Still a great book with lots of great story development, but not a lot of action. 
 Don't get me wrong, it was good and I enjoyed it. I also understand why George wrote this book in this way, but there are some drawbacks to how he did it, namely that 1) I didn't get to hear from my favorite character (Tyrion) for the entire book, and 2) there are a lot of loose ends left at the end of the book that won't be tied up until The Winds of Winter, or at best the end of A Dance with Dragons. My favorite POV character in this book is Arya, but she only has 3 chapters so that was kind of a downer. 
 I'm sure all of this is some essential stage-setting for the story, but of the four I've read so far, this one was probably my least favorite. But in the end, it's still part of this amazing series, and the story is still awesome and complex, just like George has been writing them the whole time. Looking forward to reading more Tyrion chapters in A Dance with Dragons and seeing more of the story unfold at the Wall.
