Set in the mythical land of Prydain (which bears a more than passing resemblance to Wales), Lloyd Alexander's book draws together the elements of the hero's journey from unformed boy to courageous young man. Taran grumbles with frustration at home in the hamlet Caer Dallben; he yearns to go into battle like his hero, Prince Gwydion. Before the story is over, he has met his hero and fought the evil leader who threatens the peace of Prydain: the Horned King.
