When Sol expanded into a red giant centuries too soon, Earth burned and civilization collapsed. The remnants of humanity fled outward, hollowing asteroids into massive generational starships—self-contained cities drifting between the stars.

Destiny is one of them.

Carrying twenty-five thousand souls toward Alpha Centauri, the city-ship has traveled peacefully through interstellar space for fifteen years… until the power begins to fail.

Brief blackouts.

Strange illnesses.

Whispers in the minds of the crew.

Then a signal appears.

A set of coordinates.

A beacon calling them forward.

Admiral Andrew Fairbanks must send a reconnaissance mission to investigate. But as the ships approach the source, reality itself begins to warp. Ripples in spacetime sever communication with home. Time slips. Physics bends. And the crew realizes they may not simply be facing first contact…They may be crossing into something humanity was never meant to encounter.

City in Space is a gripping hard-science-fiction adventure blending military tension, cosmic mystery, and the survival of the human race. Perfect for fans of:

The Expanse

Rendezvous with Rama

Battlestar Galactica

Classic Clarke/Asimov-style first-contact stories

When the last city of humanity sails into the unknown, turning back isn’t an option.

Because the beacon is still calling.
