One of the most inventively charming retellings of Arthurian legend, this is the final part of The Once & Future King. In these last two books, the ageing king faces the greatest challenge of his reign, when his own son threatens to overthrow him & destroy everything he's worked for. In The Book of Merlyn, Arthur's tutor Merlyn reappears. The ancient magician teaches him that, even in the face of apparent ruin, hope remains.
