After their final battle, legend tells us, Arthur and his knights went to Lyonesse, the land under the sea. Now Lyonesse is threatened by a resurgence of the Dark Powers, those mindless malevolent forces that struggle to stop the course of History.

And Jim Eckert - the Dragon Knight - and his friends are called upon to stop them.

Arthur and his knights are proud; too proud to easily accept help from Jim Eckert and his allies. But they will have help - from Jim in his dragon form, from knight-in-armour Sir Brian Neville-Smyth, from the brilliant archer Dafydd ap Hywel, and from one small hobgoblin.

The result is a wild ride: Arthurian fantasy adventure as only Gordon R. Dickson could tell it.
