In A Crack in the Sky, global warming has destroyed the earth. The seas have risen and acidified, and a Great Sickness has wiped out a huge amount of the earth's population. Humankind survives, however, in clean, perfect dome cities run by InfiniCorp. Eli Papadopoulos is the grandson of the owner of the powerful, and is expected to follow in his family's management tracks. Everything changes when Eli is contacted by the Foggers, a group of people who live outside of the domes and claim that the earth is ending, and InfiniCorp knows it.
