After Thrones I went straight to A Clash of Kings.  I got a little bogged down at the beginning but then regained my momentum and read much of it on vacation in CT.  By the end I was quite engaged again.  After one of the last chapters ended in an unexpected and disappointing way, I actually flipped ahead over the final few chapters to see which characters narrated them (hoping that what had apparently just happened actually hadn't...though I managed to miss the one that thankfully showed it hadn't).

I give it 4 out of 5.

On now to A Storm of Swords.
