God, I'm jealous of JK Rowling. There's the millions, of course (dollars and fans and copies of books sold). But not only that--she also gets to write Tales of Beedle the Bard.
This is not a Harry Potter book--Harry's not in there at all, and the style isn't that of the HP books. Instead, this is a supplemental book (much like the "school books" JK published for charity--and btw, Tales is pubbed for charity, too). The Tales are mentioned in the last HP book--and here they are presented for all of us to read, too.
Take a moment and think about the enormity of this. She's creating her world on a whole new level. We don't have to imagine the book as we read the HP story--we can hold Tales in our hand and know exactly what Ron is talking about when he mentions Babbity Rabbity. This takes story creation and fictional worlds to a whole new level, and brings readers into the fictional world at a whole new amazing level.
And that's why I'm jealous. Her millions (of everything) aside, she gets to make her fictional world more alive than almost any other author in existence.
PS--This totally isn't the traditional Writer's Review I do...but how can I talk about style and structure? It's JK. Just go buy it and revel in the experience.
