In Camelot's venerated hall, after five-and-twenty winters of King Arthur's reign, all the original Knights of the Round Table were aging, with new knights joining that force, not the least of who is Sir Galahad. He is Sir Launcelot's son. Both plague and drought afflict the land. All of the knights depart in search of the Holy Graal. Gwynevere struggles to keep her illicit affair with Launcelot secret, and Queen Morgan le Fay increases her efforts to overthrow Arthur's kingdom. Combat between champions and wars abound in this concluding volume of the King Arthur and His Knights trilogy.
