The Grey King

Will Stanton, the youngest of the immortal Old Ones sworn to defend the world against the rising power of the Dark, arrives in Wales to recover from a serious bout of hepatitis, his memory of his own magical purpose temporarily wiped clean by the illness. Sent to stay with relatives near a mountain called Cader Idris, Will slowly recovers both his strength and his buried memories while befriending Bran Davies, a strange, solitary boy with white hair and golden eyes who keeps a fierce sheepdog named Cafall. Will comes to learn that Bran is not an ordinary Welsh boy at all but the son of King Arthur, carried forward out of legend into the present by Guinevere to be raised in secret. Together they must recover a golden harp and use it to wake six ancient warriors called the Sleepers, a quest that pits them directly against the Brenin Llwyd, the Grey King, a lord of the Dark who commands the fog and a pack of grey foxes called the Milgwn, and who works less through open violence than through the ordinary human weaknesses, jealousy, fear, careless cruelty, that give the Dark its opening. The novel closes with the Sleepers woken and the immediate threat turned back, though Cooper leaves Bran's own extraordinary parentage, and the cost the Light asks of both boys, only partly resolved, carrying directly into the series' final volume.

Reading it means slowing down for dense, deliberately evocative prose steeped in Welsh landscape, language, and Arthurian legend, closer in mood to a folk tale than to the faster paced fantasy adventures many young readers expect. It is the fourth of five books in The Dark Is Rising sequence and leans on the earlier volumes for context, so readers meeting Will Stanton here for the first time may find the mythology dense before it resolves into a sense of place as vivid as anything else on this list.
