Mariam is only fifteen when she is sent to Kabul to marry the troubled and bitter Rasheed, who is thirty years her senior. Nearly two decades later, in a climate of growing unrest, tragedy strikes fifteen-year-old Laila, who must leave her home and join Mariam's unhappy household. Laila and Mariam are to find consolation in each other, their friendship to grow as deep as the bond between sisters, as strong as the ties between mother and daughter.
