Ursula LeGuin's A WIZARD OF EARTHSEA: THE EARTHSEA CYCLE, BOOK 1 is high fantasy, written by a master, one of the great works of young adult literature of the 20th century. Grounded in Celtic and Norse mythology and written in flowing, formal language, this is not a slam-bang, sword and sorcery, action fantasy: When Ged goes to battle a dragon, they negotiate an agreement instead, and the climactic moment is as quiet as a whisper. There isn't even a real villain.
So what keeps the pages turning? It's all in the details, the gradual unfolding and perfecting of another world, with its own rules and geography and magic. Ged is a fascinatingly flawed hero, and the action, though placidly paced, moves relentlessly forward toward a final confrontation that has more to do with Ged coming to understand himself than with overcoming world-dominating evil. This is a fantasy for the intellect rather than the gut.
