Sara is a philosophy professor at Kuwait University. Her relationship with Kuwait is complicated; it is a country she recognises less and less. Yet since her return from California after her mother's death, a certain inertia has kept her there. When she is accused of blasphemy – which carries with it the threat of execution – Sara realises she must reconcile her feelings and her place in the world once and for all.

Awaiting trial, Sara retraces the past, intent on examining the lives of the women who made her. Interspersed with her narratives are the stories of her grandmothers: beautiful and stubborn Yasmine, who marries the son of the Pasha of Basra and lives to regret it, and Lulwa, born poor in old Kuwait and swept off to India by her wealthy merchant husband; and her two mothers: Noura, who dreams of building a life in America, and her ayah Maria, who leaves her own children behind in Pune to help raise Sara and her brother Karim.

Spanning Kuwait, Lebanon, Iraq, India and the United States, An Unlasting Home brings to life the triumphs and failures of three generations of Arab women. At once intimate and sweeping, personal and political, it is an unforgettable family portrait and a spellbinding epic tale.
