Ever since the Switch, when the oxygen levels plummeted and most of humanity died, the survivors have been protected in glass domes full of manufactured air. Protected . . . or trapped? Or controlled? Alina's a revolutionary who believes we can save the environment. Quinn's a Premium who's never had to worry about having enough air.

In their plight for freedom, these heroes must find the best in themselves to fight against the worst in their enemies.

Led by Lewis Meriwether and Mina Clark, they hope to expand their infant nation, and to reunite the States. But the Sanctuary will not allow them to escape without a fight.
