12% done with A Storm of Swords

I think the reason why this series has grown exponentially in size from just 3 books to a planned 7 is that Martin stays true to the characters and lets them lead the story where ever it might go. Of course this means the story will then go off in unforeseen directions, but that’s the appeal here because if the author doesn’t know where a character may wind up from day to day, then neither will we.
