Finished the book last night. And if I had to review it in one word that word would be "frustrating".
Martin is still a terrific writer, able to make you love and hate characters effortlessly while creating great atmosphere and keep you involved in the story. And there are a few brilliant moments.
But he wastes so many pages and chapters on things that really don't matter. Spending hundreds of pages on getting various characters from point A to point B(whether it is geographically or mentally/emotionally). Martin can move things along at a blistering pace when he wants to, as demonstrated by the last couple hundred pages, but the first 600-700 pages are just a slog.
But none of that matters, I'm hooked for the rest of the series. On to the more controversial stuff.
Jon--Obviously not dead/going to be resurrected in some way. Which makes that scene feel cheap. I almost wish that he was actually dead dead(almost).
Aegon--There is an interesting theory on Westeros and other places that he is actually Illyrio's son. There is some compelling indirect evidence for this, although I remain unconvinced. Whether or not Aegon is who he claims to be is really not important however, what is important is what Varys tells Kevan on the last page.
"Aegon has been shaped for rule since before he could walk. He has been trained in arms, as befits a knight to be, but that is not the end of his education. He reads and writes, he speaks several tongues, he has studied history and law and poetry. A septa has instructed him in the mysteries of the Faith since he was old enough to understand them. He has lived with fisherfolk, worked with his hands, swum in rivers and mended nets and learned to wash his own clothes at need. He can fish and cook and bind up a wound, he knows what it is like to be hungry, to be hunted, to be afraid. Tommen has been taught that kingship is his right. Aegon knows that kingship is his duty, that a king must put his people first, and live and rule for them."
Knowing what we know of Martin and how he tells a story can it be any more clear that Aegon is going to die swiftly? I give him a 50/50 chance of surviving the next book, at best.
Septa Lemore--I like to thing she is Ashara Dayne, and will go into her twilight years with Barristan once they meet up. But probably not.
Jon Connington--I like the character, and along with Howland Reed he is our best chance of ever learning Jon's true parentage. While writing ADWD Martin said that one POV in the book would be from a gay character. Considering the options and the way Connington thinks about Rhaegar it seems clear it is him.
