From the #1 internationally bestselling author of The Moment and Five Days comes “the best book about Morocco since The Sheltering Sky. Completely absorbing and atmospheric” (Philip Kerr).

Robin knew Paul wasn’t perfect. But he said they were so lucky to have found each other, and she believed it was true.

She is a meticulous accountant, almost forty. He is an artist and university professor, twenty years older. When Paul suggests a month in Morocco, where he once lived and worked, a place where the modern meets the medieval, Robin reluctantly agrees.

Once immersed into the swirling, white hot exotica of a walled city on the North African Atlantic coast, Robin finds herself acclimatizing to its wonderful strangeness. Paul is everything she wants him to be—passionate, talented, knowledgeable. She is convinced that it is here she will finally become pregnant.

But then Paul suddenly disappears, and Robin finds herself the prime suspect in the police inquiry. As her understanding of the truth starts to unravel, Robin lurches from the crumbling art deco of Casablanca to the daunting Sahara, caught in an increasingly terrifying spiral from which there is no easy escape.
