This’ll be book 6. It’s called Harry Potter and the Half Blood Prince, and CNN has the details. I guess I enjoyed the Harry Potter books, although Rowling has some difficulty with plotting and pacing. I’m more glad that the books are getting kids to read, although I did like the last Potter book the second time I read it (the first time was a year ago–I read all 900 pages on one day on my trip out to Seattle, so I did rush through it a bit).
