After a world-ending hurricane nearly wipes out humanity, nations unite to reverse global warming. The solution: a global superdome of trillions of nanodrones that purify the atmosphere and control the weather — a creation that solved more problems than it was designed for. However, such power came at a cost; in order to preserve the dome, humanity now had to abandon its skies and pursuit of the unreachable infinity.

Over a century later, Celia, a 20-year-old engineering student, dreams of reaching the stars once more, inspired by her great-great-grandfather, one of Earth’s last astronauts before space exploration was illegalized. Defying the law and societal fears, Celia teams up with an old robot, a fellow engineer, and other allies to build a rocket and reignite humanity’s quest for the final frontier—confronting a world that’s forgotten how to dream beyond the safe comfort of its artificial skies.
