Number 7! Ah, the tears. Only good writing works this way.
Harry, Hermione, and Ron aren't going back to school... at the beginning of the year anyway. They are on orders from Dumbledore to find Voldemort's Horcrux's and destroy them. Harder said than done. Between running away from Death Eaters, searching, not knowing where to go, infiltrating the Ministry while Harry is the most wanted man in the country, and then realizing that the Deathly Hallows are important too... they've got their hands full.
This one is my first legit read though of the book. I've seen the movies a bunch of times and listened to the other books on audio, but this is a first. I very much enjoyed it.
I think one of my favorite parts was Kreacher's Tale. You really feel for him and are reminded that every nasty person has a back story and often times if you take the time to get to know them or their story, they'll turn out to be a decent person. Not all the time, if they choose to be that way, but there is potential for everyone and that most of the time all they want to be is understood. Kreacher is awesome and I love how he ends up leading the House Elves at the end.
I do wish though that we had been able to spread the narrative a little. Instead of solely watching it through Harry's eyes, to have gotten other's points of view. Especially during the Battle of Hogwarts. Throughout the series we've loved everyone that is in Hogwarts at the end--the good guys anyway. I wish we'd gotten more of the individual battles for Lupin and Tonks, of Kingsley, Hagrid, Molly and Arthur, and all the others. Obviously Harry can't be everywhere, but I'd have loved to get POV changes. Even POV changes when we weren't at Hogwarts at the end. To know more about what the Weasley's were doing, what the DA did in an attempt to steal the sword, Fred and George when they were still manning their shop. And most definitely more at the end. To see how everyone coped or didn't with the losses they received. Even if it was just bit and snippets of weddings, of internal changes, of grief... A page. Three paragraphs. A small bit of dialog. Something just a bit more so then we can close with them and have a more finite resolve.
But boy was it a great book. Before reading the series, I knew that there was a giant fandom for the Wizarding World. I know some fandoms can go crazy (I'm looking at you Supernatural) but now I understand why. The books were great, well done, and well made. In my opinion, there is very little lacking in the series. No, Harry Potter is not a happy book, but it is one that discusses many things that touch many people in many ways and hopefully helps us to grow. Those books are the best ones to read.
It will probably be a series I'll reread like so many before me. Enjoy.
