Flood City

Flood City is the only habitable place left on the drowned Earth, but it is also a battleground between the Star Guard who have controlled the city for decades and the Chemical Barons in their spaceships who once ruled the planet, want it back, and are now preparing to destroy it; the future will depend on Max, his sister Yala of Flood City, and Ato, a young Chemical Baron who just wants to keep his twin brother alive and not hurt anyone--and somehow these natural enemies will have to work together to save Earth.
