The story of the Argonauts continues in the middle of pulpmaster Jeff Deischer's Worlds Collide "human trilogy", which follows Philip Wylie and Edwin Balmer's original two novels, When Worlds Collide and After Worlds Collide. As Christmas approaches, a mystery attack on Athens, the new home of Earthmen, devastates the five domed cities. The humans must race against their unseen enemy to find a way to defend their home and stop the attacks before they are wiped out.
