Twelve-year-old Ethan must take command of a fractious flying squadron charged with finding a new Resister base, while being pursued by alien invaders.

NEBULAR is a science fiction series that takes you to the year 2113. It is an era in which nation states are a thing of the past. United in the Solar Union, humanity faces its last great challenge: the exploration of the outer Solar System. The Union Fleet already maintains scientific outposts on the distant moons of the gas giants Jupiter, Saturn, Uranus and Neptune. Private companies are prospecting for raw materials and spaceships shuttle between the planets. The causes of earlier civilisational setbacks, such as wars, disease and poverty, have been overcome. Around ten billion citizens of the Solar Union populate the Earth, and another 250 million people settle in the growing colonies on the Earth’s moon and Mars. The furthest outpost from Earth is on Neptune’s moon Triton. It is a frigid world populated mainly by scientists and private companies. The crew’s main task is to explore the Kuiper Belt with its dwarf planets, also called the Outer Ring. Astrophysicists use the remoteness of the celestial body to advance the search for extraterrestrial life. The scientists of the new SETI project use their receiving antennas to examine neighbouring stars for potential radio signals from alien civilisations. A total of around two thousand men and women are on duty at the Triton Base. The icy deserts on Jupiter’s moon Europa, the dust storms of Mars and the primordial hydrocarbon seas on Saturn’s moon Titan have been seen by space travellers from Earth with their own eyes, but so far they have not found extraterrestrial life. One of humanity’s most important goals remains to make peaceful contact with alien civilisations in space. Unconsciously, most scientists hope that these life forms are similar to us and that communication is possible. So far, the search has been unsuccessful, but this does not rule out the possibility that they exist in the vastness of space and are already observing us.

In the distant future, society has all but eliminated the need for a sentient workforce. Thanks to an all-powerful AI network known collectively as Titan, humanity is now free to indulge in an era of unprecedented peace and prosperity. But one day, hobbyist psychologist Seika Naisho gets a job offer from a mysterious man by the name of Narain Srivastava--one of only a handful of people in the entire world who is still traditionally employed. Narain wishes to enlist her expertise in the wake of a sudden and inexplicable malfunction in the AI network: as a therapist for Titan itself.
