Book was good. I will now re-read it to pick up details I didn't bother with. Personally, I was rooting for Harry's death but was totally upset when it actually happened... and then realized I still had about 50 more pages to read =P So I guess the length of a book can be a spoiler haha
Btw, I wonder how Griphook felt when he realized Godric's sword was no longer in his possession... nasty shock, I might surmise.
