Speaking franklly, when I was diagnosed with cancer, eighteen months ago, I was very concerned that I'd have no sort of closure to a whole bunch of things, including getting to the end of ASOIAF as well as Scott Lynch's Locke Lamora books and even seeing David Tennant end his reign as Doctor Who! Of course I also worried about less important things such as missing my family and so on!!!
Since then, I've found out my condition is controllable, and while I don't have a clue whether I'm going to last for six months or ten years (though it's likely to be closer to the former than the latter), I don't think I'll see the end of GRRM's series. I hope I get to read ADWD, but any thing after that would be an unexpected bonus. I won't give up on the series though; I enjoy the writing far too much - even if I wasn't as impressed with AFFC as the other books.
xLORDSNOWx, The ending of the Dark Tower series wasn't bittersweet...it was damned disappointing! I don't know if I could beg for info on how something ended, using my condition. It just seems a little whingy!
And I'm not as concerned about Bran and Dany as I am Jaime and Jon. they are my favourite POV chapters along with Tyrion!
