Inversion by Aric McBay

On a mysterious green planet renewed by fire, vibrant collectivist communities have long lived in harmony with both its strange ecosystem and each other—until the day imperialist forces arrive.
Raised in one of the non-hierarchical nomadic societies on the planet of Germinal, young Char and her family tend to this commons, rich in culture and biodiversity, through principles of reciprocity, ritual, and attention to the balance of their ecosystem. But they must forever travel to stay just ahead of the natural phenomenon that marks their world: a wall of fire that approaches like clockwork, bringing both loss and renewal with it. She is the first to spot the arrival of landing vessels, and soon her way of life is upended by militaristic invaders whose intentions are far beyond her worldview.
