Haunted by her mother's death, sixteen-year-old Penny sleepwalks by night. By day, she peddles bootleg vodka to rich kids looking for kicks on the wrong side of Brooklyn Bridge, a place reeling in total economic meltdown, strict curfew laws, and violent disarray. Penny's chance meeting with Quinn, a rabble-rouser dabbling in counterculture graffiti, sets in motion a deep love affair and the start of a seemingly impossible revolution. Inspired by a childhood memory, the two of them craft powerful messages hidden in the folds of hundreds of paper airplanes. They plan to launch them from the rooftops of derelict buildings even as the unforgiving militia hunts them from below. Will hope take flight in a crumbling world, or will their efforts devastate them all?
