[WillAdams]

A couple of other, slightly off-beat (but wonderfully done) Arthurian novel (at one point in time I was trying to stay up on reading all of them, but then the quality got off) recommendations:

Arthur, King --- Dennis Lee Anderson --- Arthur as a WWII Spitfire pilot --- delightfully well done
Black Horses for the King --- Ann McCaffrey --- an exploration of why so many taverns in England are named for black horses
Excalibur --- Sanders Anne Laubenthal (not Elizabeth Ann Scarborough as I'd originally written ---- my thanks to Slite for the correction) --- the Welsh in pre-Columbus America

and I'll second the suggestions of Susan Cooper's _The Dark is Rising_ pentalogy --- one of my favourite series and Gillian Bradshaw's books.
