In a world shattered by alien invaders, humanity clings to survival in scattered settlements, isolated and desperate.

When the ships arrived, there were no warnings. No communication. Only bloodshed. The blue-skinned, gilled invaders unleashed havoc from space, executing their plan to terraform Earth. But something interrupted the process, leaving the planet fractured and desolate.

Over ninety percent of humanity was wiped out in the Fall, and only the lucky and the resourceful survived, scraping by in scattered settlements.

Yet survival was just the beginning. The aliens didn’t leave; they landed.

Armed with advanced technology and a relentless hunger to crush any remaining humans, the Gills gave no quarter. But the human race is nothing if not resilient. From their ramshackle settlements, the survivors fought back against an overwhelming alien force, refusing to fade into extinction.

Ronin had been wandering alone for years, carrying a secret that could change the course of the war. All he needed was a settlement with a working radio—just one call to rally humanity’s last hope. A secret he carried.

Then he found Reunion. A settlement that might finally offer him a home…and the chance to strike back. But the Gills weren’t finished.

And they’d stop at nothing to take everything from him once again.
