The last person Alice Shipley expected to see since arriving in Tangier with her new husband was Lucy Mason. After the horrific accident at Bennington, the two friends - once inseparable roommates - haven't spoken in over a year. But Lucy is standing there, trying to make things right. Perhaps Alice should be happy. She has not adjusted to life in Morocco, too afraid to venture out into the bustling medinas and oppressive heat. Lucy, always fearless and independent, helps Alice emerge from her flat and explore the country. But soon a familiar feeling starts to overtake Alice - she feels controlled and stifled by Lucy at every turn. Then Alice's husband, John, goes missing, and Alice starts to question everything around her: her relationship with her enigmatic friend, her decision to ever come to Tangier, and her very own state of mind.
