"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 a late-night knock on the door breaks the spell. Ruth and G.H. are an older couple -- it's their house, and they've arrived in a panic. They bring the news that a sudden blackout has swept New York. But in this rural area -- with the TV and internet now down, and no cell phone service -- it's hard to know what to believe. Should Amanda and Clay trust this couple -- and vice versa? What has happened back in New York? Is the vacation home, isolated from civilization, truly a safe place for their families? And are they safe from one another? Leave the World Behind explores how our closest bonds are reshaped -- and unexpected new ones are forged -- in moments of crisis" -- Publisher description.
