Reading Harry Potter Book 7

Well I went to bed around 2am but couldn't really sleep so I got up around 7am and started to read the final Harry Potter book. I was conflicted because I want to read it and find out what happens but then I don't want to read it to fast and finish it because this is the last. I managed to read two chapters the morning I got it and I read another nine chapters today. I figure if I read about 12 chapters a day I can read it in three days. Will see how that works. So far the book is awesome... so dark and so good. JK has really outdone herself and I'm only on the first 11 chapters... I can't wait to read more.
