Hee-hee! Sorry but there never was an oh moment for me coz i kept cheating and would always try to read the end of the book when the suspense gets too much for me . With DH, i just made sure that Ron would survive coz i read in a forum before the book came out that he was gonna die, and well, i had to make sure, hadn't i?
but the ending for the goblet of fire was one heck of good writing wasn't it? when voldemort emerged from the cauldron, the wand duel and harry's escape. GOF truly deserves to be the 5th in BBC's list of top 100 novels of all time!
