“Sometimes I say my name out loud, just to remember what it sounds like.” Sixteen years ago, a plague swept through the United States of America, locking those infected in a permanent state of heightened emotion. They called it the Feeling. The lucky ones got placed in Quarantine Zones, where they exist in relative peace. the unlucky ones, like Wander, got left behind, with no choice but to take each day as it comes. When faced with raiders, fighters, and smilers, survival relies on following the rules.

1. No names.
2. Fly, or die.
3. Always keep moving.
4. Trust no-one.
5. Take what you can.
6. Don't travel at night. Wander's only alive because she follows these rules, but everything changes the day a boy named Dagger stumbles into her life. He’s on the run from the smilers and, against her better instincts, Wander decides to help. There has to be more to living than being alive and, to find out what it is, Wander's going to need to break every rule she's ever held sacred.
