Death or Glory
 The story begins on a human colony world of Volga, populated by ex-Russians, Americans and Germans. While there is a government of sorts on the planet, most disputes are settled Wild West style. All males own a weapon since there are plenty of bandits. Life is chaotic and, at the same time, simple. Everything changes when prospector Roman Savelyev (his personal blaster has the words "Death or Glory" engraved) finds a strange black box with a big red button in one of his mines. After musing on how clichéd his situation is, he cannot help himself and presses the button. The box disappears the morning after. Several days later, a giant starship suddenly appears and enters Volga's atmosphere to come to rest above the island where the box was found. Not long after the races of the Alliance trace the heavy gravitational tracks of such a huge ship having penetrated the Barrier and showing up in orbit. The aliens assume that the ship belongs to a disappeared ancient race they call the Departed Ones. They are followed by an armada of Imperishables who are also interested in the strange vessel. The Alliance dares to investigate the ship and use it as a weapon. However the results are disappointing: ship's only controls are "biosuits" — organic structures wrapping an organism to perform a full contact — and they are designed only for Humans. Pressed for time as Imperishable are soon to arrive, the Alliance comes to a plan of capturing as many Humans as possible and using them to defeat the attack. But although it's easy to destroy the planet, to capture human "savages" proves to be a difficult task: humans are able to hold off the invaders whose orders are to capture the homo not kill them. Eventually though, most humans are captured and brought to the strange ship. Alliance scientists use their captives to reactivate the ship's systems, especially weapons to use against the Imperishables. However, the humans are able to take over the ship using the neural connections of the "biosuits" and obliterate the alien fleets. Volga is destroyed in the same battle, and the alien ship jumps into deep space. On the ship, dubbed Volga by the humans for their destroyed colony, some parts of the crew (mostly the former colony administration) begin plotting against their captain (Savelyev) and his command crew for the control of the ship. As it turns out, the ship selects the command structure based on the person who pressed the red button who becomes captain. Those closest in mindset to Sevelyev are given high command positions. Most bureaucrats and thugs have very different personalities from the captain and are assigned to low positions (something they do not like). At the same time, Savelyev is attempting to figure out the ship's true nature, as he is the only one with unrestricted access to Volga's systems. Once the attempted coup is put down, Savelyev reveals to his friends that the ship is a parasite, adapting its controls to whoever calls to it. Each time a person uses a biosuit, they experience euphoria, but ship also takes something of the person. Eventually, the ship consumes the crew and begins to seek out a new race to command it. The origins of the ship are unknown. Savelyev speculates that it is either a product of some ancient race or of the galaxy itself to act as an antibody against invaders, in this case the Imperishables. Eventually, the Alliance catches up with the ship and propose a deal: humans help them drive the Imperishables out of the galaxy, and the Alliance "uplifts" all humans (whom they now call a latent race) to the status of full members of the Alliance. Savelyev, as the human representative, agrees to it, ensuring a place for humans among the stars. The three other novels which take place in the same universe are called Black Relay, Legacy of Giants, and No One but Us (the latter two are usually published together as War for Mobility).
