Recently, I finished A Clash of Kings, and I've moved on to A Storm of Swords. As much as I'm enjoying the series, I'm going to have to take a break from A Song of Ice and Fire after that, since I'll finally be ahead of the HBO series that's been prompting so many spoilers around the web. I've got, like, a bajillion other things to read. I'll get back to it, don't worry. I do have the next two books, after all.
A Clash of Kings is what it says on the can. We start out with the four kings that we had at the end of the last book. Then one is assassinated by magic - hooray for more magic - and then another one pops up on the other side of the continent. Though, now that I think about it, Greyjoy sure is taking his dear sweet time about conquering things, especially given that the iron men are pretty much straight up viking/klingon/those-bad-guys-from-The-Chronicles-of-Riddick analogues: Kill people and take their stuff.
The main impression that I have from A Clash of Kings comes from a few chapters during which I felt rather upset not only that Bran and Rickon had been killed off - especially before Bran got to really utilize his
Oh, also, I was frustrated to no end with Arya's incompetence regarding her three kills. I kind of wanted to see that chaos that would be wrought if she'd spent one on Tywin Lannister. Furthermore, I was just plain surprised that she didn't use one on Gregore Clegane: He was responsible for the deaths of several of her fellows, her own capture, and that of her fellow survivors, and he's nearly unkillable.
I was also glad to get some progress on that stuff beyond The Wall. (It seems to be paying off quite well in A Storm of Swords, too.)
