Tally and Grace are teenage sisters living on the outskirts of society, dragged from one no-hope town to the next by their fugitive father. When an explosion rips their lives apart, they flee separately to the city. The girls had always imagined that beyond the remote regions lay another, brighter world: glamorous, promising, full of luck. But, as each soon discovers, if one arrives broke, homeless, and alone, the city is a dangerous place—a place where commerce and surveillance rule, and undocumented people like themselves are confined to life’s shady margins. Now Tally and Grace must struggle to find each other and survive.
