Finished reading

Whuiii.. just finished reading Harry Potter and The Deathly Hallows. Great story...(yes it was great).It contains 37 chapters and 638 pages (the pdf), thick book i say. I started reading it for about 2 weeks, I took some time. The story was enough to satisfy my curiosity about things that it didn't revealed in the previous chapters. Things like why Snape killed Dumbledoor, what Dumbledoor look like when he's young, and others. Too bad that J.K Rowling didn't continue any of Harry Potter's book again.
