And in the shadows, a dark, ancient powers awaken.

“Shadow of the Star Dragon” is the fourth Star Dragon story -- science fiction written with an 1950s pulp flair -- and the continuing adventures of the Star Dragon and the Accord Constabulary into the world of art fraud and criminal masterminds. Be sure to read “Birth of the Star Dragon,” “Call of the Star Dragon,” and “Flight of the Star Dragon” first, and be on the lookout for “Trial of the Star Dragon” to bring this epic series to completion.
