Third in the series of Burroughs-like adventures among the Jovian moon system. Jandar is faced with the insurmountable task of freeing his beloved Darloona from the dreaded Sky Pirates. But his course is altered, as first the fearsome red Perushtarians, and then the slaver of Narouk, threaten his with any number of horrid torments. He must escape both, and he must do it in condition good enough to effect the rescue of the princess.
