In the fourth and last book of the Once and Future King, King Arthur is getting old, his round table old has a few members left, most of them lost to the grail. Lancelot and Guenevere are still lovers though subtle warnings from the king. Then finally after many years Mordred, Arthur son from his sister comes forth and accuses the Queen of her affair. Lancelot had to run to escape from Mordred but the queen was tried and convicted, she was to be burned. Lancelot came to rescue her from the stake but killed many people in the battle. A few of them being Mordred's uncles, this really got him mad and got the king to preform war against Lancelot. The Pope declared that Lancelot and Guenevere were both true to the king and pardoned the accused. The result was a very long siege at Lancelot's castle while Mordred was temporary King back home, and he finished the plan he started since he accused the queen. Mordred went to the people and said that the King had been killed in battle, and therefore took the crown. As soon as Arthur heard this he went back home to regain the crown, the morning of the battle the book ends with Arthur telling his Paige to pass on his story.
T. H. White's writing style is very good it keeps to going through the plot, but keeping you informed and understanding what is going on. Although this is not my preferred genre, the book is very good and details the story of Arthur very well. The theme that came from this book was how power corrupts people. This always relates back to life as an archetype, from Caesar, to Hitler. The story of King Arthur is in various forms but this one was very through and telling making it very convincing that this story was the true version.
