4 a.m., New York City. A silent disaster. There is no flash of light, no crumbling, no quaking. Each person in New York wakes up on an unfamiliar block when the buildings all switch locations overnight. The power grid has snapped, thousands of residents are missing, and the Empire State Building is on Coney Island—for now. The next night, it happens again. Esme Green and Arjun Varma work for the City of New York's Emergency Management team and are tasked with disaster response for "The Unmapping." As Esme tries to wade through the bureaucratic nightmare of an endlessly shuffling city, she's distracted by the ongoing search for her missing fiancé. Meanwhile, Arjun focuses on the ground-level rescue of disoriented New Yorkers, hoping to become the hero the city needs. While scientists scramble to find a solution—or at least a means to cope—and mysterious "red cloak" cults crop up in the disaster's wake, New York begins to reckon with a new reality no one recognizes. For Esme and Arjun, the fight to hold the city together will mean tackling questions about themselves that they were too afraid to ask—and facing answers they never expected. With themes of climate change, political unrest, and life in a state of emergency, The Unmapping is a timely and captivating debut.
