Richard Linklater, eat your heart out. The Sword in the Stone is the original Boyhood. We don't even know just how important Wart is until the very end of the first book. He's only "Wart," or "The Wart" (a gross nickname that rhymes with "Art,") but we're not told until the end that that's short for Arthur, as in King Arthur.
The first book is all about Wart's coming of age. We see how his foster family, magical tutor, and various folks around the Castle of the Forest Sauvage shape his identity, and how he learns valuable lessons that will make him into the king that he is destined to be throughout The Once And Future King.
To a lesser extent, the books are also about the coming of age of several other significant characters, including Lancelot and Galahad.
