The Earthsea Quartet - Ursual LeGuin

Studied the first book when I was twelve; didn't remember much about it. The writing style is very dense, but not in an unfriendly way. It just goes very deeply into things. Some great fantasy concepts here, such as the language of magic, where everything is called by its "true name" rather than words being simply signifiers, so speaking it gives you power over reality. It struck me that each book is very self-contained and different from the others, unlike many fantasy series that give the impression of really being one long book cut into manageable sections. Deep and interesting and well-written; I still prefer The Left Hand of Darkness.
