Echoes of Chonos

In a not-so-distant future, the world is divided between gleaming "Sky Cities" floating above the clouds and the shadowy "Earthbound" slums left behind on the surface. Seventeen-year-old Tessa Ray is a brilliant coder from the Earthbound zone, hacking old tech to survive and dreaming of a better life. When she stumbles upon a mysterious AI artifact buried in a scrapyard, she accidentally activates a message from the future—her own voice, warning of a disaster that will destroy both worlds.
