GRRM is a master storyteller, that's really all there is to it. "A Knight of the Seven Kingdoms" has a little something for everyone - from action and intrigue to romance and comedy. Having just read Ivanhoe, you can really tell that GRRM is heavily inspired by Sir Walter Scott (see my Ivanhoe review) but he really elevates the craft to a whole new level and is a much easier read for a modern audience. The audiobook narration is terrific as well.
