Now begins the final battle of the Prophets and the Pah-wraiths within the nightmarish realm of nonlinear time -- as the greatest epic adventure in the saga of Deep Space 9 -- reaches its staggering conclusion....

As predicted in ancient Bajoran texts, the Celestial Temple has been restored, ending normal space-time existence for all except Captain Benjamin Sisko and those trapped on the Starship Defiant and the Klingon warship Boreth. But as apocalyptic war rages between the Prophets and the Pah-wraiths, one last chance for survival beckons -- a return to Deep Space 9.

Yet, in the realm of nonlinear time, it appears that there are two possible times at which Sisko and his allies can return to the station: on the day of the Cardassian Withdrawal, or on the day six years later when DS9 was destroyed. But which choice will lead to the triumph of the Prophets? And which to eternal victory for the Pah-wraiths? With time literally running out and the fate of the universe in his hands, Sisko now must confront his own personal inferno -- in order to change the past and restore the present, he must be ready to make the ultimate sacrifice... his future....
