The novel powerfully demonstrates how women find strength in unity, particularly through the profound relationship between Mariam and Laila. Despite facing brutal domestic violence, oppressive social norms, and the harsh realities of life under Taliban rule, their bond becomes an unbreakable force that helps them survive and ultimately triumph over their circumstances.

Through multiple regime changes and social upheavals, the story explores how political violence seeps into personal lives. Yet amidst the darkness, moments of tenderness and sacrifice illuminate the possibility of breaking these cycles. The characters' personal struggles mirror Afghanistan's larger journey, showing how hope can persist even in the bleakest circumstances.

The theme of motherhood runs deep throughout the narrative, examining both biological and chosen maternal bonds. Mariam's evolution from a child bride to a maternal figure for Laila, and Laila's own journey into motherhood, showcase how maternal love can transcend blood ties and inspire ultimate sacrifices for the sake of others.
