L'ultime rivage

Book Three of Ursula K. Le Guin's Earthsea Cycle. Darkness threatens to overtake Earthsea: the world and its wizards are losing their magic. Despite being wearied with age, Ged Sparrowhawk - powerful 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.
