Emi Vargas, whose parents helped save the world, is tired of being told how lucky she is to have been born after the climate crisis. But following the public assassination of a dozen climate criminals, Emi’s mother, Kristina, disappears as a possible suspect, and Emi’s illusions of utopia are shattered. A determined Emi and her father, Larch, journey from their home in Nuuk, Greenland to New York City, now a lightly populated storm-surge outpost built from the ruins of the former metropolis. But they aren’t the only ones looking for Kristina.
