Popular, young adult book series?
What I've read:
Maximum Ride Series
Chronicles of Narnia
Harry Potter Series
Artemis Fowl Series
City of Ember Series...
Shadow Children Series
A Great and Terrible Beauty series..
I like to read series books, so please only recommend books with at least three books in the series. BIG books, like at least four hundred pages in each book.
I don't mind if there are sex scenes or anything, but I'm looking for more young-adult like books.
Also, I want a book series that actiony, mysterious, adventurous, fantasy, and romancy. And sorta on the popular book series list, so I can talk to people about it.
Please don't say the Pendragon series/Series of Unfortunate Events because I hated those books...
Sorry for being so picky!
