Fantasy Literature

I tend to read things pretty quickly.

The first 3 books, each of them took maybe 2 days a piece to read. Basically, I finished the box set close to a week. A Feast of Crows took me about 3 days.

I bought the box set, so it was a quick read. I got my hands on Dance with Dragons, a while back. I started reading it, but I put it down a few times, and up to now, I haven't bothered picking it back up.

I've read quite a few books in between, but I just can't seem to feel inclined to picking it back up and reading it through.
I guess, when he started using different names on some of the POVs, it didn't quite interest me as much.

Also, the fact that I know it is probably going to take another 3-5 years for him to finish another book, and then another 5-7 years after that... I feel like, I don't know why I am reading this, when he would probably not finish it in his life time.
