The electrifying space epic continues as Anna and John Sheridan battle deadly foes at opposite ends of the universe. The dedication of the new Babylon 5 Station is fast approaching, and desperate enemies intend to see it end in catastrophe. The fate of the fledgling space alliance lies in the hands of John Sheridan, newly appointed captain of the spaceship Agamemnon. His orders are to stop the attack. Unless he first gets to the bottom of the near-mutinous behavior of the Agamemnon’s unruly crew, Sheridan and his spaceship will share Babylon 5’s doom. Time is also running out for his wife Anna, headed to Z’ha’dum aboard the Icarus. Young, beautiful, and brilliant, she was thrilled to be appointed chief science officer of the follow-up mission to this mysterious planet on the edge of the known universe, where artifacts rumored to hold stupendous powers have been discovered. But the offer she could not resist threatens to become a dark destiny she cannot avoid, for an unimaginable horror lies somnolent on Z’ha’dum–and the monstrous consequences of disturbing the sleeping evil will haunt every living thing in the cosmos. . . .
