Just finished Harry Potter and the Deathly Hallows and I must say that the ending of the series was, in my opinion, brilliant. Quite an enjoyable read, and I wouldn't say that I'm a particularly fervent fan. Now that it's over I'm sad to see the story end (as I always am with such tales).
My favorite character, by far, was Severus Snape -- tragic, noble, brave, and desperately misunderstood.
