In this epic Star Trek: Deep Space Nine adventure set during the Dominion War, Captain Benjamin Sisko must unravel the mystery of the lost Orbs of the Prophets before the fate of the entire galaxy hangs in the balance.

Welcome, Emissary. As Benjamin Sisko picks his way over the wreckage that was his new command as a thousand questions, countless problems, dire reports, and the soon-to-be-familiar harangue of the Bajoran Liaison Officer clamor for his attention. From the shadows, a monk steps out and greets him. With all that has happened, it is no small wonder that Sisko takes that greeting and relegates it to the back of his mind.

Six years have passed. Despite the recent retaking of Deep Space 9, it seems that the Federation is losing the Dominion War. As commander of a front-line post, Sisko focuses on the war effort, paying little attention to the latest rumor: the fabled lost Orbs of the Prophets have been recovered, and legend holds that they are the key to unlocking a second wormhole—a second Celestial Temple. In war, sometimes the little things you don't notice are your undoing.

Now Benjamin Sisko, a man of science and a Starfleet officer—and also the Emissary—is swept up in the ultimate war of good versus evil. Every decision he makes draws him, his family, and his crew into the abyss. Faced with the possibility that he alone must decide the fate of life in the galaxy, Captain Sisko must unlock the truth behind the Orbs of the Prophets or the future, the past, and even the present will wink out of existence!
