In a world that has forgotten about nature, two girls live on opposite sides of society. Skyler exists above the clouds in a haven of boundless technology, while Ivy is a Groundling, roaming the surface of the Earth and eking a living from the rubble of the past. Then Ivy makes a discovery that changes everything and brings their lives crashing together. A tense, heart-pounding and empowering read about corruption, environmentalism, and what we would do if nature gave us a second chance.
