Re-reading Harry Potter

I am in between books I've requested at the library and so I have started to re-read the Harry Potter books. This idea came to me after the last book came our earlier this summer. There seemed to be a jump in personalities etc in the 6th book and I decided I couldn't remember the books well enough and the movies of the first three can cloud the truth of the books. So I am really enjoying them again and have found that there a slight sinews I missed the first time that I am picking up this time! I suppose I will make them, maybe not an annual read like The Lord of The Rings, but ever few years!
