Definitely Harry Potter hands down, I've read all the books except for two of them. They were practically the only books i would read and i would finish one in just a few days.
I personally like the Redwall Series even if it is the same recipe over and over agiain. But somtimes that recipe is really good and it has excellent/engaging characters and creative enviroments.
The wand choses the wizard XVERB... but the sword and bow have no master, harry is a small boy... but the hobbits are smaller, Gandalf is a powerful wizard... But Dumbledore is Merlin first class, Potter world have flying cars, mythical beasts, a fantastic school, and the dark lord... Lord Of The Rings have Legolas.
