"In a land destabilized by unsafe air, wildfires, floods, viruses, supply shortages, and homegrown terror, Cass is raising three small children by herself in the city. Her husband, Nathaniel, has gone all too willingly to serve as a medic in an overseas war. His absence, and Cass's isolation, has brought her into an exhausted but harmonious rhythm with the children; while it's a frightening time, there is also a surprising, quiet tenderness in living on the edge of societal collapse. When things start to feel more dangerous in the city, Cass evacuates with the children to her mother-in-law's house deep in the countryside. Initially, it's a place of safety, but her mother-in-law's erratic behavior and increasing grip over the children worries Cass, and so they flee again to a commune on the coast. It's an idyllic place, but Cass comes to suspect this seemingly harmonious community has a dark underbelly ... Against a wider backdrop of a world imploding, it [this novel] is an exploration of hope and fear, beauty and joy, as well as seismic betrayal."-- Provided by publisher.
