A Wizard of Earthsea (Earthsea Cycle,1) Ged, the greatest sorcerer in all Earthsea, was called Sparrowhawk in his reckless youth. Hungry for power and knowledge, Sparrowhawk tampered with long-held secrets and loosed a terrible shadow upon the world. This is the tale of his testing, how he mastered the mighty words of power, tamed an ancient dragon, and crossed death's threshold to restore the balance.
Re-reading the Earthsea books has reminded me how much I love them... A Wizard of Earthsea is part of the original trilogy, and is followed by The Tombs of Atuan and The Farthest Shore. I first read (and re-read) them from the library, starting when I was twelve or so, before eventually getting my own much-loved copies. Le Guin added two more volumes years later: Tehanu, and The Other Wind, which are quite different in tone.
“It is no secret. All power is one in source and end, I think. Years and distances, stars and candles, water and wind and wizardry, the craft in a man's hand and the wisdom in a tree's root: they all arise together. My name, and yours, and the true name of the sun, or a spring of water, or an unborn child, all are syllables of the great word that is very slowly spoken by the shining of the stars. There is no other power. No other name.”
