Amazon.com Book Description (ISBN 0812562712, Mass Market Paperback)

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; 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-armor 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.
