The Farthest Shore: Le Guin Ursula K.

Darkness threatens to overtake Earthsea: the world and its wizards are losing their magic. Despite being wearied with age, Ged Sparrowhawk - Archmage, wizard, and dragonlord - embarks on a daring, treacherous journey, accompanied by Enlad`s young Prince Arren, to discover the reasons behind this devastating pattern of loss. Together they will sail to the farthest reaches of their world - even beyond the realm of death - as they seek to restore magic to a land desperately thirsty for it.
