Son and daughter of diplomats in Cairo, the gentle Serena Pasha and Mark Holt are privileged and attractive, growing up in a magical world of champagne breakfasts and midnight picnics at the pyramids. Their lives entwined since childhood, they grow ever closer as adults. Yet Serena's hand has been promised not to Mark, but to his brother, Greg. As World War II speeds closer to Cairo, a shocking accident gives these young lovers a second chance—but with this chance comes terrible danger. Egypt is threatened not only by the German army but by nationalist forces within Cairo determined to end the British occupation at any cost. The country torn apart, and enemies everywhere, Mark and Serena's love is tested to the limit.
