T H White - The Once and Future King - All 5 Books - Unabridge

Quartet of novels by T.H. White, published in a single volume in 1958. The quartet comprises The Sword in the Stone (1938), The Queen of Air and Darkness--first published as The Witch in the Wood (1939)--The Ill-Made Knight (1940), and The Candle in the Wind (published in the composite volume, 1958). The series is a retelling of the Arthurian legend, from Arthur's birth to the end of his reign, and is based largely on Sir Thomas Malory's Le Morte Darthur. After White's death, a conclusion to The Once and Future King was found among his papers; it was published in 1977 as The Book of Merlyn.
