Galaxies collide in a thrilling new series from bestselling author Ian Douglas, as the last humans in the universe face off against a new threat 2162. Thirty-eight years after first contact, Lord Commander Grayson St. Clair leads the Tellus Ad Astra on an unprecedented expedition to the Galactic Core, carrying more than a million scientists, diplomats, soldiers, and AIs. Despite his reservations about their alien hosts, St. Clair is deeply committed to his people—especially after they're sucked into a black hole and spat out four billion years in the future. Civilizations have risen and fallen. The Andromeda Galaxy is drifting into the Milky Way. And Earth is most certainly a distant memory. All that matters now is survival. But as the ship's Marines search for allies amid ancient ruins and strange new planetary structures, St. Clair must wrap his mind around an enemy capable of harnessing a weapon of incomprehensible power: space itself.
