What if the sky was deadly?
Seventeen-year-old Fin has never stepped foot on the surface of the Earth. Working the mines deep below has been the only life she has ever known, an underground existence of sweat and monotony in service to the Enhanced Human Coalition—the genetically-modified who control the underground from the world above. Every Dweller underground understands that you serve the EHC up top, or you don’t eat.
But now, Fin and her friends discover a stolen piece of EHC tech that modifies genetics, giving them the abilities of those up top—varied levels of increased strength, intelligence, and adaptation to the surface’s harsh conditions. The theft of this technology triggers a manhunt, forcing them to flee to the most dangerous place they could possibly go… aboveground.
Can she save a world broken in two?
