On an ordinary Saturday in a California suburb, Julia awakens to discover that something has happened to the rotation of the earth. The days and nights are growing longer and longer; gravity is affected; the birds, the tides, human behavior, and cosmic rhythms are thrown into disarray. In a world that seems filled with danger and loss, Julia also must face surprising developments in herself, and in her personal world: divisions widening between her parents; strange behavior by her friends; the pain and vulnerability of first love; a growing sense of isolation; and a surprising, rebellious new strength. With crystalline prose and the indelible magic of a born storyteller, Karen Thompson Walker paints a breathtaking portrait of people finding ways to go on in an ever-evolving world.
