I read the first book, and enjoyed it a great deal. And then I looked over at my wife, who, at the time, was waiting for the next Wheel of Time novel, and wondering if the author was going to drop dead before he finished the series.
So, I put Martin on the shelf, and I intend to pick up the series again when he's well and truly finished - either by finishing it or by he himself being finished.
That's what I'm afraid of as well - that Martin will die before the series is finished.
Heck, I excitedly bought the last book from the series the weekend it came out. I sat down to read it and then realized that it had been so long since the previous book had come out that I had forgotten all but the lead characters. I put it down in frustration and said I won't read it again until either the series is finished or I have the time to re-read the first three books in a reasonable time frame and then actually remember things for books 4 & 5.
