Leave the World Behind by Rumaan Alam

It's summer and Amanda and Clay are looking forward to a week away with their son, Archie and daughter, Rose. They've rented a house in a remote area of Long Island. On their second day there, the owners of the home--G.H. and Ruth--arrive, saying that a blackout has happened in New York City and asking if they can take refuge at their home. With a media blackout and no cellular service, the group is in the dark about what's really going on, but it doesn't look good. Leave the World Behind explores all the characters' reactions to the situation and their interactions with each other in a unputdownable story. Similar in feeling to Bird Box and in character development to Lake Life and also a great choice for book clubs.
