Mahmoud’s passion for his wife Fereiba, a schoolteacher, is greater than any love she’s ever known. But their happy, middle-class world—a life of education, work, and comfort—implodes when their country is engulfed in war, and the Taliban rises to power.

In Kabul, we meet Fereiba, a schoolteacher who puts her troubled childhood behind her when she finds love in an arranged marriage. But Fereiba’s comfortable life implodes when the Taliban rises to power and her family becomes a target of the new fundamentalist regime. Forced to flee with her three children, Fereiba has one hope for survival: to seek refuge with her sister’s family in London.

Traveling with forged papers and depending on the kindness of strangers, Fereiba and the children make a dangerous crossing into Iran under cover of darkness, the start of a harrowing journey that reduces her from a respected wife and mother to a desperate refugee.

Eventually they fall into the shadowy underground network of the undocumented who haunt the streets of Europe’s cities. And then, in a busy market square in Athens, their fate takes a frightening turn when Fereiba’s teenage son, Saleem, becomes separated from the rest of the family. Without his mother, Saleem is forced, abruptly and unforgivingly, to come of age in a world of human trafficking and squalid refugee camps.

Heartbroken, Fereiba has no choice but to continue on with only her daughter and baby. Mother and son cross border after perilous border, risking their lives in the hope of finding a place where they can be reunited.
