Brienne no sale en Danza de Dragones.
Cito del blog de George R. R. Martin:
So what's left? Plenty. A huge book, just a hair shorter than A STORM OF SWORDS, as I said. The final count shows that we've got 73 chapters, told through the eyes of (gulp) sixteen different viewpoint characters. I could tell you who they are, but then I'd have to kill you.
Actually, though, it might be easier to tell you who they aren't. Sansa, Sam, Aeron Damphair, Arianne, and Brienne have no chapters in A DANCE WITH DRAGONS. Several of those characters had chapters written, completed, and polished that have been moved into THE WINDS OF WINTER. Part of that editorial process I mentioned up above.
Back when I split A FEAST FOR CROWS into two books, I said in my infamous afterword, "Meanwhile, Back at the Wall..." that Tyrion, Dany, and Jon Snow would be back in the next book, and so they are. Those three characters dominate A DANCE WITH DRAGONS. Out of 73 chapters, 35 concern their exploits; sixteen viewpoints, aye, but just three of them make up almost half of the book. The next largest chunk o' chapters belongs to an old POV character who has been missing for a couple of books, but now returns to us... rather the worse for wear.
Yes, some of the characters who were featured as POVs in A FEAST FOR CROWS will reappear, since the timeframe covered by DANCE extends well beyond that of FEAST. Tyrion is not the only Lannister with a viewpoint. Cersei and Jaime will have chapters as well, though... be warned... not a lot of them. Arya is also on hand. And we'll check in with Bran and his companions as well, on their long cold trek beyond the Wall. There are two Dornish POVs (one old, one new), and three ironborn(all previous POVs).
And there are some new viewpoint characters. Some of them are new CHARACTERS, introduced for the first time in this book. Others are established characters, but new VIEWPOINTS; they have been around, but you've never gone inside their heads before. Once, a few years back, I said that I only meant to introduce one new viewpoint character in the book. Which just goes to show why I should never sound off about these things before the book is done. In the end, I wound up with.... hmmm, let me count 'em... one, two, three... ah... FOUR new viewpoint characters. And that doesn't even include the Prologue and Epilogue. So...
