Arthurian themes

In case any of you are fond of stories with this theme to them, I wanted to recommend a few for you.
By Mary Stewart: (In order of reading)
The Crystal Cave
The Hollow Hills
The Last Enchantment
The Wicked Day
In case you have not read these, without spoiling them for anyone, they are the story of Arthur as seen by Merlin

Also, by T.H. White, The Once and Future King, also the story of Arthur, but with no one narrator throughout.

I found all of these to be a lot of fun to read (although there is a scene concerning Morgause in The Once and Future King that will make you cringe), and I particularly love the way Stewart describes a her scenery and surroundings. One tends to really feel inside the work.
