Enna Martinez is a 12-year-old girl living a comfortable life when a phenomenon deemed ‘The Polar Storms’ swallows the globe whole. From pole to pole, unprecedented drought squeezes dust from the earth. Gradually—then all at once—social order breaks down. As hate-crimes creep ever nearer to their Anchorage home, Enna's family flees into the Alaskan wilderness. The family scraps together a tenuous pioneer lifestyle—but then one day, Enna’s little sister disappears. As her parents plummet into grief, a now-adolescent Enna must rise to the role of hunter, gatherer, and caretaker for the family. She learns to harness the storms and predators that once terrified her, and in doing so, discovers a strange magic underpinning her survival.
