A middle-class white couple and their two teenage children from Brooklyn rent a house on Long Island for a week’s vacation near the beach. On their second night, there is a knock at the door and the owners, a black couple from Manhattan, arrive, seeking shelter because there is a widespread power outage in the city. Phone service, internet, television, all stop working. Without any information, and with increasing dread, the two families navigate uncertainty and strange natural occurrences. The author uses this setup to explore issues of race, class, and generational differences. A compelling read which provides more questions than answers.
