Harry Potter is a great creation of marketing. There are dozens of similar books and stories but none of those brought the authors so much money. I respect that.
In my own humble opinion, Harry Potter books suck ass. I wish Al-Qaeda would switch over to bombing Harry Potter fans instead
HP was really interesting but now i realize it was a waste of time.I wouldnt advice my kids reading it
By the time that your kids will be born ( assuming that you do not have any children now), there will be another HP created by some other author.
