Over half way through the next book

I've now read 53.7% of part 1 of 'book' 3 of the Song of Fire and Ice series.  So much s I bought the second part a couple of days ago to continue the epic story.  Interestingly enough, it was at number seven in Waterstone's Leadenhall Market store twelve years after it's first publication.  George R.R Martin will be pleased.  And quite rightly so.  A very good read.
