Born the bastard son of a Welsh princess, Myridden Emrys -- or as he would later be known, Merlin -- leads a perilous childhood, haunted by portents and visions. But destiny has great plans for this no-man's-son, taking him from prophesying before the High King Vortigern to the crowning of Uther Pendragon . . . and the conception of Arthur -- king for once and always.
The dark forces that were repulsed in "Out of the Silent Planet" and "Perelandra" are massed for an assault on the planet Earth itself. Word is on the wind that the mighty wizard Merlin has come back to the land of the living after many centuries, holding the key to ultimate power for that force which can find him and bend him to its will. A sinister technocratic organization is gaining power throughout Europe with a plan to "recondition" society, and it is up to Ransom and his friends to squelch this threat by applying age-old wisdom to a new universe dominated by science.
