Captain Keyes has succeeded in forging an uneasy alliance - at the cost of making some powerful enemies. Now, he's wanted throughout the galaxy. Even worse: they're after his ship. His enemies inside the UHF have realized that only the Providence stands even a slight chance of stopping them.

GSI (Gettnor Space Industries) is beginning to investigate our solar system and mine the asteroids. Aircraft and automobile companies are beginning to switch over to thrusters from their more traditional products. New uses for thrusters are popping up in the healthcare and sports industries. However, at Epsilon Eridani, a race of aliens has so overpopulated their own solar system that they must move many tens of billions of their people to another system before overcrowding destroys them.

Mike Cohen has it all figured out. A successful venture capitalist, he’s got billions in the bank, a lifestyle any New Yorker would kill for, and - if he plays his cards right - a shot with his cute, punky coworker. But everything changes when the life-altering technology he's developing lands him in the middle of a global conspiracy, and the only way to save himself, his loved ones, and his tech is to embed the highly experimental Brainocytes in his own brain. Brainocytes transform the human experience, making you smarter, faster, and more powerful.

Tiona, Vaz's daughter, is starting grad school in physics, has a "bad boy" musician boyfriend, and does her own strange variety of charity work at a homeless shelter. Her professor has her start work on a project to try to achieve high-temperature superconduction by doping the graphene membranes her lab partner has figured out how to precipitate.

Trapped on an alternate Earth, the combined crews of a crashed Russian spaceship, a British expeditionary force and a group of strays from the future must work together to survive, escape and discover what led them to this point. All are from parallel universes where small changes in history led to different realities, and the tensions between the groups are rising.

> Disc picks up right after Vaz and Tiona's invention of an apparently reactionless drive in Tiona.
