The Fourth Book of Earthsea

'She is unique. She is legend’ THE TIMES’Le Guin is one of the singular speculative voices of our future, thanks to her knack for anticipating issues of seminal importance to society’ TLSBook Four of Ursula K. Le Guin’s award-winning Earthsea Cycle Years ago, they had escaped together from the sinister Tombs of Atuan — she, an isolated young priestess; he, a powerful wizard. Now she is a farmer’s widow, having chosen for herself the simple pleasures of an ordinary life. And he is a broken old man, mourning the powers lost to him through no choice of his own. Once, when they were young, they helped each other at a time of darkness and danger and shared an adventure like no other. Now they must join forces again, to help another in need — the physically and emotionally scarred child whose own destiny has yet to be revealed.
