NeutiquamErro – Granted, Harry Potter is a masterpiece. However, you may want to take into account that not everything you consider Kosher would be considered kosher by all. I know for certain that a couple of posters here feel that the Harry Potter series isn’t kosher at all (specifically Order of the Phoenix and Half Blood Prince). That said, I somehow doubt Sparkly would consider it unkosher.
If you did like Harry Potter, you may want to try Percy Jackson, Heroes of Olympus, Artemis Fowl.
