It's stardate 2378, and Benjamin Sisko has finally returned from the Bajoran Wormhole omnipotent—but his godhood is failing with every minute. Sent by the Prophets on a mission to the deepest parts of space aboard the U.S.S. Theseus, he witnesses the unthinkable: someone is killing the gods. And only Sisko and his motley crew of Starfleet members from every era of Trek can stop them.
In its escape from the Delta Quadrant, the U.S.S. Theseus has landed in an unknown sector of space that appears safer—if not a hundred years younger—than their own. There, the crew receive a signal from an oncoming ship: the U.S.S. Enterprise. Captain James T. Kirk is hailing. The two crews join together in the race against Lore’s wave of destruction, convinced there must be some countermeasure that will save their universes from complete annihilation. But will their combined bravery and brainpower be enough? Or is it already too late for both their timelines?
