T.H. White

Camelot

The plot of his illegitimate son Mordred to gain the throne, and Guinevere's growing attachment to Sir Lancelot, threatens to topple King Arthur and destroy his "round table" of knights.

The Sword in the Stone

Wart is a young boy who aspires to be a knight's squire. On a hunting trip he falls in on Merlin, a powerful but amnesiac wizard who has plans for him beyond mere squiredom. He starts by trying to give him an education, believing that once one has an education, one can go anywhere. Needless to say, it doesn't quite work out that way.
