The crew of the "Starship Defiant" is trapped in a future in which the Pah-wraiths have triumphed - as the greatest epic adventure in the saga of Deep Space Nine continues . . .
In the last days of the twenty-fourth century, caught in the crossfire of the apocalyptic confrontation between the Bajoran Prophets and the Pah-wraiths, Captain Benjamin Sisko and his crew face what might be the final millennium. On one side, the Pah-wraiths' new emissary, Kai Weyoun, promises his followers that when Bajor's two celestial temples are restored as one, all beings in the universe will ascend to a new and glorious existence with the True Prophets. On the other side, the scientists of Starfleet predict that when the two Bajoran wormholes merge, they will create a Warp 10 shock wave of infinite destructive power.
With the Federation on the brink of collapse, and Starfleet consumed by Admiral Jean-Luc Picard's obsessive quest to build the largest starship ever conceived, Sisko enters the ultimate race against time for the biggest stakes of all - the survival of the universe itself.
