Glastonbury Tor is a love story of Jonah Bentley. Jonah is a young man from Wyoming who runs off in the early 1940s, joins the Royal Air Force, and flies Spitfire aircraft against the Germans. His best friend and wingman, David Hill, introduces Jonah to his sister, Barbara. Jonah and Barbara fall in love. They are tested in the fire of war. This is a story of love, loss, life, and death. It centers around the hill known as Glastonbury Tor—the supposed burial place of King Arthur and the actual site of Avalon.
