If you're going to reference others works, get your info correct. There are 5 books in the original Percy Jackson series, not 7. (There are 7 in the Harry Potter series.) Not a difficult fact to check. I will grant that Riordan has added to the series, but if you count the newest ones, you should also count the Heroes of Olympus series since PJ plays a major role in it before the newest books.
