The Wizard of Earthsea:

The first book of Earthsea by Ursula Le Guin is a tale of wizards, dragons, and terrifying shadows.

The Island of Gont

The island of Gont is a land famous for wizards. Among them, some say the greatest—and surely the greatest voyager—is the man called Sparrowhawk.

Sparrowhawk's Journey

As a reckless, awkward boy, Sparrowhawk discovered the great power within him—with terrifying consequences. Tempted by pride to try spells beyond his means, Sparrowhawk unleashes an evil shadow-beast upon his land.

The Quest

Only Sparrowhawk can destroy the shadow-beast, and his quest to do so leads him to the farthest corner of Earthsea.
