(From the publisher):
The Yaksha were once the rulers of all Mars, and even today the legends of their days of glory thrilled both young and old, the seekers of adventure and those willing to be satisfied with dreams of great men and great deeds. The Yaksha were gone, long turned to dust, but in their place remained pieces of ancient marvels, hints of ancient technology. The vaults of the Yaksha were crowded with their marvelous machines, though none still lived who knew their secrets ... and it was to the vaults of the ancients that Michael Kane came, seeking the cure for the Green Death. For the Yaksha had left more than memories to the people of the Mars of today; they had left their most fearful curse. And only the long-dead ancients could save the living of today!
