i finished it!!!
it was incredible, i've now decided that my favourites are the third and the sixth book.

and i think it's wonderful how i was able to achieve that kind of frozen state, reading every word over and over really slowly at the climax, despite having had the ending spoilered to me before. i didn't know it was snape who did the killing though, that part came as a surprise.
and it also occured to me the idea of harry being a horcrux. that would be a spectacular ending to the series in my opinion.
also, two things that piqued my curiosity:
1. kreacher and dobby are still able to disapparate and apparate in school grounds, outside of the great hall! did i miss something? (forgive me if this was already explained in a previous book, i haven't read them in a while and it was hard to catch up when i first started reading the half blood prince)
2. remember zacharias smith? the kid in hufflepuff? also, remember that other lady that voldemort got the hufflepuff antique from? her last name was smith. i don't know if anybody else noticed that, but i am almost sure that zacharias smith is going to be involved if harry has to eventually find the hufflepuff antique horcrux.
