It's 2032, and in this near-future America, all citizens are chipped and everyone is tracked. It's almost impossible to survive as an undocumented immigrant, but that's exactly what sixteen-year-old Vali is doing. She and her family have carved out a stable, happy life in small-town Vermont, but when Vali's mother's counterfeit chip starts malfunctioning and the Deportation Forces raid their town, they are forced to flee. Now on the run, Vali and her family are desperately trying to make it to her tía Luna's in California, a sanctuary state that is currently being walled off from the rest of the country. But when Vali's mother is detained before their journey even really begins, Vali must carry on with her younger brother across the country to make it to safety before it's too late.
