When bohemian artist Miranda meets British ambassador Finn in the ancient stone streets of an Islamic city, the course of her life alters in extraordinary ways. Their marriage gives her the luxury to paint whenever she wants, a staff to wait on her, and a young daughter she adores, but she loses the freedom to wander where she likes and to meet the Muslim women she is secretly teaching to paint. Her husband also makes Miranda a target: One sunny afternoon while hiking in the mountains, she is brutally kidnapped.

As Finn struggles to save his family and his career, and Miranda grows close to a stranger's child in captivity, the secrets he and Miranda have each sought to hide place them and those who trust them in peril. Not even freedom could restore the happiness that once was theirs.
