Query: The best fantasy books I've ever read!

I'm ten years old, and so far this book and its sequels (Deep Wizardry, High Wizardry, etc.)are among the best fantasy books I've ever read (I've read a lot of books). The magic in them is much more complex than it is in the Harry Potter books. It's not just a wave of your wand and some Latin words; it's geometric shapes and strange words in Speech (the wizarding language) written in the sand, wizard's knots and paragraphs to say in Speech. I also like the idea of a manual that teaches Nita and Kit (the main characters) wizardry, instead of a teacher. The characters also seem more real than they do in some other fantasy books (at least the human ones do). This is a great series!
