Discomfort is the point
Alam starts his novel on the most ordinary of notes. Amanda and Clay and their two kids, Archie and Rose, are headed to a rural area of Long Island for a summer vacation. They've rented a house, a very nice one, on an isolated country road and plan on limited contact with the world. For the next few days they swim in the pool, hit the small local grocery store and make a trip to the beach. Nothing too exciting, but that's the goal. Late on the third night that goal is upended when there's a knock on the door.
