Speaking of re-reading the books: after reading Books 1-5 over the course of a week, I was completely hooked. But, I think it took about 2 years for Half Blood Prince to be released. So, I re-read, re-read, re-read. I think I got through 1-5 about 4 times each. During the summer, I'd take a book, lounge chair and cooler of beer to the back yard. I'd read, drink, and catch rays. Since it was about 95 degrees each day, of course I'd sweat like a pig while reading. As I'd rest the book in my lap or on my stomach, the pages absorbed my sweat...which leads to molded, mildewed books. The set we have in our house is the replacement set for the books I ruined.
I just don't get the love for these books. Not that they are bad. I am glad they inspired a lot of kids to read that might not otherwise read. I read them, they are reasonably interesting. There is just such better science fiction books around.
