Millenia ago, an apocalyptic battle was fought in the Alpha Quadrant. The losers were banished, but what became of the victors? The Federation is threatened by this ancient mystery when a battered and broken version of the USS Defiant is found, frozen for five thousand years, in an icy cloud of cometary debris. Captain Sisko and the crew of Deep Space 9 are summoned to answer the most baffling question of their lives: how and when will their ship be catapulted back through time to its destruction? And does its ancient death mean that one of the combatants in a primordial battle is poised now to storm the Alpha Quadrant? Only the Bajoran wormhole holds the answer – and the future of the Federation itself may depend on the secrets it conceals.
