Two humans and a robot on their own in the Alpha Centauri system: Marchenko, Adam and Eve have found asylum on a planet inhabited by aliens. They could spend the rest of their lives here in peace. But apparently there are many more people who, like them, have been sent to alien systems without a return ticket and without being asked - castaways with uncertain fates who need their help. Their alien rescuers generously offer to take them on a search in one of their spaceships.

No one has ever ventured deeper into space than the four astronauts of Shepherd-1. The aim of their mission is to witness the creation of the cosmos. Using the sun as a lens, they are to align a flock of probes in such a way that the moment of the Big Bang becomes visible. For astronomer Christine, this is a dream come true. So she is bitterly disappointed when the first images are obscured by a kind of veil that prevents any insight. She works obsessively to find a solution, but when she finally succeeds in lifting the veil, she sees something that would have been better kept hidden...

And what will they find when they finally emerge?

As if nearly burning up in a freak accident on her way to Earth wasn't bad enough, Daisy had a whole mess of other trouble on her plate. Big trouble. And she was going to get to the bottom of it if it was the last thing she'd do, which it was starting to look like it very well might be. The thing is, Daisy had a simple rule for space travel. Don't blow up, and so far she'd been managing to abide by that, but mere survival wasn't enough.

Ian Stevens, director of the Deep Space Research Institute, isn’t interested in conducting research just for the sake of research. While the rest of the world - including the US Government - thinks that’s the DSRI’s sole mission, Stevens is actually interested in more - he wants manned space travel and the colonization of the moon. With NASA defunct, few scientific probes are being launched, and no one even talks about human spaceflight anymore. Stevens is out to change that.

Space explorers and planet-bound scientists alike prepare for mankind's first encounter with alien intelligence.

A planet in the endless emptiness of space, far from the warmth of any sun. And yet there are people who populate its vast caverns, living, working and loving. Since time immemorial, they have been on course for Andromeda, the neighboring galaxy of the Milky Way. This is the prophecy of the ancients, the one goal that unites them all, their cult. But then the unthinkable happens: the journey stops because the planet enters the orbit of a mysterious object that can't be seen in any telescope.

It is 2056. Mathematics professor Elisabeth Gabai is fascinated by multi-dimensional forms that have no equivalent in reality. Then, her boss sends her to the site of an artifact that might have come straight from her theories—or from the technology of an advanced civilization. Twenty-eight years earlier, physicist Max Webber is hell-bent on improving Einstein’s theories of relativity. His latest concept seems flawless, except it predicts the end of humanity. The extinction of Earth can only be prevented if Max can locate a multi-dimensional object.

In the year 2031, a robot probe detects traces of biological activity on Enceladus, one of Saturn's moons. This sensational discovery shows that there is indeed evidence of extraterrestrial life. Fifteen years later, a hurriedly built spacecraft sets out on the long journey to the ringed planet and its moon.
