well, as they say, even the best marketing strategies cant sell your product if it is not good. I have read all 7 Harry Potter books, and believe that all books are very well written. The USP of the books is not the magic, but the underlying human emotions of the characters. Hogwards can be replaced by any school in UK(or for that matter India). The story is more about freindship, courage and emotions. However sticking to the topic, I believe Harry Potter is indeed a good book, and rather than marketing strategies selling the book, it is the other way around.
