I took 5 and a half hours. Living in Singapore, our release time was 7.01am. I got my book at 7.48am by special delivery and I wrapped the book up first before reading. *grin* Dad called me to lunch at about 11.50am and I started again at 12.30pm finishing at 2.30pm. Lol. Dad didn't expect me to finish it so soon! He has it now and can't seem to put it down! He hasn't read the first 4 books. Never too late to become a Potter fan I always say! Wheee!
