If you somewhat liked Harry Potter...you Might want to investigate Terry Pratchett's books. Harry Potter is boring and infantile in comparison.
I have watched a Harry Potter movie! Arrgh! How can you stand it? I've read - well I only managed to make it down one page of a HP book. Of course if you are around 10 years old...HP is perfectly okay. FYI... I have enjoyed reading sci-fi and fantasy for many years. LOTR and the books of Terry Prachett are FAR more entertaining and sophisticated...FYI.
I guess to serious fantasy lovers...hp is nothing. I don't mean to be rude to author... Rowling?
