alaxy. Humanity was slowly making their way out from Earth to the planets and asteroids of the Solar System, exploring and mining and founding colonies. The mining ship El Cavador is far out from Earth, in the deeps of the Kuiper Belt, beyond Pluto. Other mining ships, and the families that live on them, are few and far between this far out. So when El Cavador's telescopes pick up a fast-moving object coming in-system, it's hard to know what to make of it. It's massive and moving at a significant fraction of the speed of light.

The ice is coming. It was the last thing we expected, but the world is freezing. A new ice age has dawned. Billions have fled the glaciers. A cataclysmic war is coming. In orbit, a group of scientists are running the Winter Experiments, a last-ditch attempt to understand why the planet is cooling. None of the climate models they build make sense. But then they discover an anomaly, an unexplained variation in solar radiation...and something else. Close to the burning edge of the sun, they catch a fleeting glimpse of something that shouldn’t be there....

In 2204, humanity is expanding into the wider galaxy in leaps and bounds. Cutting-edge technology of linked jump gates has rendered most forms of transportation - including starships - virtually obsolete.

And all seems wonderful - until a crashed alien spaceship of unknown origin is found on a newly located world 89 light-years from Earth, carrying a cargo as strange as it is horrifying. To assess the potential of the threat a high-powered team is dispatched to investigate. But one of them may not be all they seem....

Now his life depends on learning what their plans are, and how he can stop them.

Jeff Dolan always wanted to be an astronaut. After helping a private space company build a ship that can travel to Saturn's largest moon in five months, he gets his chance. Shortly after launch, a devastating malfunction forces Jeff and the crew to make a choice: continue to Titan or go back home. As the truth about their mission unravels, one thing is clear: Someone on Earth knew about the system flaw and covered it up. Yet surviving the journey isn't the crew's only concern. Even if they make it to Titan, they will face another problem: Something is already there.

On humanity's first extra-solar mission, the exploration vessel Magellan, or, as she prefers, "Maggie", discovers an alien artifact. Deciding that finding advanced alien life is too important to ignore, Captain Allison Ridgeway chooses to return to Earth while ordering her crew to reverse engineer technology far beyond anything back home. Meanwhile, at mission control, the governments struggle to maintain the existence of aliens a secret while also combating bureaucracy, the military industrial complex, and everyone else who wants a piece of what could skyrocket humanity into a new technological age.

In the near future, political tensions between the United States and China are at an all-time high.

Geoff and his friends live in Phocaea, a distant asteroid colony on the Solar System's frontier. They're your basic high-spirited young adults, enjoying such pastimes as hacking matter compilers to produce dancing skeletons that prance through the low-gee communal areas, using their rocket-bikes to salvage methane ice shrapnel that flies away when the colony brings in a big (and vital) rock of the stuff, and figuring out how to avoid the ubiquitous surveillance motes.

In 1978, the first group of space shuttle astronauts was introduced to the world - 29 men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir Riding Rockets, strips the heroic veneer from the astronaut corps and paints them as they are - human.
