Not much I can say about this one that others have not said. For a generation of readers and authors, I feel this story defined reading pleasure, but that's not really enough of a statement. The climax of the story with the wand lore, the intricacy of the plot, the motivations of the characters (especially Snape & Dumbledore), Rowling's world-building, and the selfless actions of the very flawed human protagonist are all exclamation points for me. I can read this story forever. :-)
