I've finished reading the last Harry Potter book. Have you?
If you have, then an interesting discussion of the book is happening over at Cheryl Klein's Blog.
She was the continunity editor of the book and discusses the parts of the book she loves.
Right now there are two Harry Potter posts. Look for these titles:
Back to Harry
Some thoughts on Deathly Hallows
Mark her blog to go back to later if you haven't finished the book yet. Major spoilers that are true. Great stuff.
