Five hundred colonists have been sent across the stars to settle an alien planet. Vat-grown in a dream-like state, they are educated through simulations by an artificial intelligence and should awaken at thirty years old, fully trained, and ready to tame the new world.
But fifteen years into their journey, an explosion on their vessel kills most of the homesteaders and destroys the majority of their supplies. Worse yet, the sixty that awaken and escape the flames are only half-taught and possess few useful survival skills.
Naked and terrified, the teens stumble from their fiery baptism ill-prepared for the unfamiliar and harsh alien world around them. Though they attempt to work with the colony A.I. to build a home, dissension and misery are rampant, escalating into battles for dominance.
Soon they find that their worst enemy isn’t the hostile environment, the A.I., or the blast that nearly killed them. Their greatest danger is each other.
