There's a short article today in the Times Picayune about J.K. Rowling's visit to New Orleans. Not too much new stuff here, but she did answer questions about the fate of a character or two (that didn't appear in the other interviews). I also like the quotes from the students at the very end of the article.
J.K. Rowling's U.S. tour ends on Friday with two appearances in New York- one for school children and one for the public. For other articles about her tour so far check this post and this one.
