Despite an OBE for services to children's literature, and the fact that books like The Weirdstone of Brisingamen and Elidor are the kind of absorbing childhood fantasy that reverberates into adulthood, to view Garner as a children's writer is reductive. He puts it best when he says: "I do not write for children, but for myself. Adolescents read my books. By adolescence, I mean an arbitrary age somewhere between 10 and 18." It's an in-between group, and Garner's books are likewise poised between passion and detachment, intensity and alienation, blunt modernity and ancient myth. His style is stripped-down, yet shares dialect and linguistic relish with much older works. "The language of my childhood and of my native culture is, technically, North-west Mercian Middle English," he has said - the language of the Gawain poet. The layers of local history and a precise sense of place are paramount in his work.

He has been writing for over 40 years; each book is a lengthy project as he pours so much research into it (learning Welsh for The Owl Service, for example). Eventually, "I feel a jolt within me and I hear quite without any understanding; I hear words, which I put down". Not all his work is fantasy - the Stone Quartet follows four generations of Garner's family from the mid-19th century to the second world war.
