The year is 2104.

Nearly thirty years ago, the wealthy and powerful escaped a dying Earth, fleeing to Command One, a vast space station drifting through the stars in search of a new home. Over the years, ships returned to collect those deemed worthy. Now only one final ship remains. It is humanity's last chance to leave a collapsing planet behind.

Sam Powell, his wife Mel, daughter Iris, and mother Carla have survived in isolation in the Colorado wilderness. But when they intercept a transmission about the final departure from New York, they know this is their only chance to escape.

The journey across a broken America will push them to their limits. Ruthless survivors, violent cults, mutated wildlife, and the unforgiving Earth itself stand in their way. Every step threatens their lives and tests the bonds that hold them together.

Set in the universe of Euphoria (2022, Ukiyoto), Serenity reveals the story of those left behind. Where Euphoria explored humanity's future among the stars, Serenity is a raw, gripping portrait of survival on the planet they abandoned.

Because freedom is never promised. And survival always comes at a price.
