Ms. Rowling is truly amazing. I am happy with how the series ends and think that she did an excellent job tying up the loose ends and generally making the story make sense.
I'm not going to go into much detail, because I don't want it to be a 'spoiler' but this is a truly remarkable series about good vs. evil. If you like fantasy stories involving magic then this one is for you! Check out Harry Potter today! :)
Cheers! Happy reading!
