I'm still trotting along at a brisk pace on my aSoIaF reread. I'm well into A Feast for Crows, now. This is where the structure of the tale changes and gets interesting from a logistical perspective. In Book 4, we're short POV chapters from several of our favorite characters, including Jon, Dany, and Tyrion. Instead, we have POVs in the south of Westeros, centering around King's Landing, the riverlands, and Dorne, as well as the Iron Islands. We get Cersei's point of view, and see her incompetence and flaws as a ruler first-hand. We get Brienne's story, which I'm not sure the purpose of, remembering how it plays out. We get Arya in Braavos, which is cool.We get Sansa and Littlefinger in the Vale, and we get action in Dorne and among the Ironborn, which is also cool. I'd forgotten that Victarion was a POV character in Feast. I remember his chapters from Dance being entertaining.
All in all, book 4 really seems like the beginning of the second grand movement in the series. The war of five kings has for the most part wrapped up, and the remaining players are turning their focus elsewhere, to the north and the Others, to the east and its dragons, or inward, with the case of the Lannisters and King's Landing. Sansa, Arya, Tyrion, Samwell, Jon, Jaime and others have had major character-defining turning points both internally and geographically, setting the stage for further action on down the road. It's an exciting time in Westeros, even if this book and the next are light on major shakeups in comparison to book 3, especially.
