A Dance With Dragons
 

I am roughly 100 pages from finishing this book and I believe it is the best out of the five. Please check it out.

I read the first 4 in one go a couple of years ago. I would have to read them all again before I read #5 and they weren't that great the first time.

If Martin finishes the whole thing off before he dies I might consider picking up volumes 5through 12/whatever.
