Return from The Void

ALL GALACTIC INTELLIGENCESAre endangered by the invisible alien attackers, the Unseen. A defence against this incomprehensible & diabolical enemy must be found if, planet by planet, the inhabitants of uncounted worlds are not inexplicably to disappear from the face of space like the pitiful population of ghost world Mirsal 3.  What, indeed, happened to the Mirsalese people? No one knows the answer yet to the wholesale vanishment of the populace of Mirsal 3 but Mirsal 2 now takes stage front & centre as the most likely spot to confront & apprehend the uncanny opponent.  A trio of Terranians volunteer to risk their all to save a doomed world in— RETURN FROM THE VOID!
