Do you think that if the HARRY POTTER series is over all of their fan will be on the PERCY JACKSON series

Maybe some of the fans will, but they probably don't like just one of the series. They probably are fans of both series, and just because Harry Potter is over that doesn't mean that the fans will stop liking the series. Tey might keep liking it forever.

I converted from HP. It is still dear to me, but PERCY JACKSON IS BETTER!!!!!!!!

I, and all friends of mine who like Percy, agree that while it fills the void left by HP and is a great, great story, it's nowhere near HP.

Rick might have spent a lot of time researching for the book (considering he teaches Greek history that shouldn't have been too hard), but JKR spent a lot more time THINKING. That's why HP books, with their intricate plot twists, are a way better read than PJ books.

Don't get me wrong. I'm a Percy fan, all right. But in no universe would I suggest that it is better than HP.
