Used. Hardcover. Rumaan Alam’s *Leave the World Behind* turns a chic Long Island rental into a claustrophobic crucible when the homeowners arrive with panic in their eyes and tales of a total blackout in the city. Without Wi-Fi, cell service, or functioning screens, these two families are left to parse paranoia, power outages, and profound discomfort in the dark. It is a supremely suspenseful social thriller that brilliantly skewers modern anxieties about class, race, and our fragile reliance on technology. You will want to flip the pages faster than the flickering power grid, provided you can handle the creeping dread of the unknown.
