Acid rainstorms have transformed New York City into a toxic wasteland. Thousands have died and thousands more have been left stranded inside the five self-contained boroughs under military control. In one apartment building, an unlikely family of humans and ghosts survives. Mira reels from a devastating breakup with her partner Mal who is lost in the faraway expanse of Queens. A second generation Chinese American now back at home with her mother, Mira calls out to the empty airwaves with her HAM radio in the hopes of reconnecting with Mal, or connecting with anyone at all. Across the hall, Shin, a ghost cockroach, replays his lost life, and a headless man named Sad falls in love. Mira's mother is plagued by furious dreams alongside Grandpa Why, now a rambunctious ghost. As the world around them worsens, each character must learn to redefine what it means to live, die, and love at the end of the world.
