Believe it or not, some of the most original fantasy that I have read recently is out of Scholastic Books (y'know, the little papers that come home with kids from school to buy books.)
These include:
The Pendragon Series (The Merchant of Death, The Lost City of Faar, the Never War and the Reality Bug) by DJ MacHale (Not Arthurian):

The Keys to the Kingdom (Mister Monday, Grim Tuesday) series by Garth Nix:

The Seventh Tower (The Fall, Castle, Aenir, Above the Veil, Into Battle, The Violet Keystone) series, aslo by Garth Nix:

All 3 of these series are very original and imaginative and have influenced my DnD campaigns to a greater of lesser extent. Just because these books are geared towards the "Harry Potter" crowd (which I enjoy as well), does not mean that they are dumbed down, just less graphic as far as violence and such goes. Still, plenty of action, intrigue and way cool magic!
...and no, I do not work for Scholastic
