Virginia lent me the latest Harry Potter. I liked it very much, it was
very well written. It was sad, but a very good story nonetheless. I
think it was the right length and the details were just interesting
enough to keep  me going along the plot. I won’t spoil it for
people who haven’t read it, but the plot was unpredictable (I was
guessing, even when I sorta suspected what would happen), and the
characters were well done.  I am looking forward to the next book.

Meanwhile, I found that Wikipedia has great in-depth coverage of all
the books. We are ALL awaiting the movie (HP4) very eagerly!
