Amanda and Clay head out to a remote corner of Long Island expecting a vacation: a quiet reprieve from life in New York City, quality time with their teenage son and daughter, and a taste of the good life in the luxurious home they’ve rented for the week. But with a late-night knock on the door, the spell is broken. Ruth and G. H., an older couple who claim to own the home, have arrived there in a panic. These strangers say that a sudden blackout has swept New York, and—with nowhere else to turn—they’ve come to the country in search of shelter.

But with the TV and internet down, and no cell phone service, the facts are unknowable. Should Amanda and Clay trust this intruding couple—and vice versa? What has happened back in New York? Is the vacation home, isolated from civilization, a truly safe place for their families? And are they safe from each other?

Suspenseful and provocative, Rumaan Alam’s third novel is keenly attuned to the complexities of parenthood, race, and class. Leave the World Behind explores how our closest bonds are reshaped—and unexpected new ones are forged—in moments of crisis.
