I don't know why I don't give this book a fifth star. I've read it twice, and both times were done with shameless rapidity. I read it so fast the first time that I forgot almost all of it. The second time was done almost as quickly, and I'm sure I'm going to forget a lot of it again. 
 Anyway, this book closes up the canon very nicely. There are hardly any loose ends lying about when everything is shut down at the end. There are a lot of characters in the overall story through the seven books, and of course they aren't all accounted for at the end of this one, but J.K. Rowling gives an occasional interview and tells us what's going on with them. At any rate, I'm satisfied, and highly suggest checking this out if you haven't already.
