This book is about three survivors in a world with 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 is shattered. I recommend this book for ages 11 and older.
