Ashen smog has sealed off the sky for years. The ruins of the old world rot in the radiation zone, and humanity's last remaining chance at survival is confined to seven floating domes.
Huang Ye is the lowest-ranking scavenger in the Rust Belt, scraping together half a ration bar by stripping metal from the old world. Then an accident puts a pass to the Seventh Dome in his hands. The strange-patterned water-purification chip is more than a ticket to survival; it also holds a secret the dome's officials are desperate to hide: someone is secretly destroying the last batch of radiation-free seeds, while people from the lower levels are being used as "radiation adaptability test subjects."
Beneath the Seventh Dome's "civilized order" lies a predation even colder than the Rust Belt. Huang Ye is forced to leave behind his life as a scavenger concerned only with self-preservation and assemble a team of mechanics, exiled officials, and mutants. They will seize water plants, expose the cover-up, and even cross the deadly radiation zone in search of the legendary "Green Core," said to restore the land. Because on this desperate earth, the Seventh Dome is no endpoint: it is the first spark to rekindle the embers of civilization.
