Sisters Rose and Gameela Gubran could not have been more different. Rose, an Egyptologist, married an American journalist and immigrated to New York City, where she works in the Metropolitan Museum of Art. Gameela, a devout Muslim since her teenage years, stayed in Cairo. During the aftermath of Egypt's revolution, Gameela is killed in a suicide bombing. When Rose returns to Egypt after the bombing, she sifts through the artifacts Gameela left behind, desperate to understand how her sister came to die, and who she truly was. Soon, Rose realizes that Gameela has left many questions unanswered. Why had she quit her job just a few months before her death and not told her family? Who was she romantically involved with? And how did the religious Gameela manage to keep so many secrets?
