The world has no air. Ever since the Switch, when the oxygen levels plummeted and most of humanity died, the survivors have been protected in a glass dome full of manufactured air. If you want to live, you pay to breathe. But what if you can't pay? And what if you think everything could be different? Alina's a revolutionary who believes the Resistance can save the environment, can break free, and she's on her first mission. Quinn's a Premium who's never had to worry about having enough air. His best friend, Bea, is an Auxiliary who's never worried about anything but having enough air. When all three cross paths and walk into the Outlands with two days' worth of oxygen in their tanks, everything they believe will be shattered.
"In a barren land, a shimmering glass dome houses the survivors of the Switch, the period when oxygen levels plunged and the green world withered. A state lottery meant a lucky few won safety, while the rest suffocated in the thin air. And now Alina, Quinn, and Bea--an unlikely trio, each with their own agendas, their own longings and fears--walk straight into the heart of danger. With two days' worth of oxygen in their tanks, they leave the dome. What will happen on the third day?"--Provided by publisher.
