Half of a Yellow Sun is a novel by Nigerian author Chimamanda Ngozi Adichie that re-creates a seminal moment in modern African history: Biafra's impassioned struggle to establish an independent republic in Nigeria during the 1960s, and the chilling violence that followed. The novel tells the story of the Biafran War through the perspective of the characters Olanna, Ugwu, and Richard.

Thirteen-year-old Ugwu is employed as a houseboy for a university professor full of revolutionary zeal. Olanna is the professor's beautiful mistress, who has abandoned her life of privilege in Lagos for a dusty university town and the charisma of her new lover. And Richard is a shy young Englishman in thrall to Olanna's twin sister, an enigmatic figure who refuses to belong to anyone.

As Nigerian troops advance and the three must run for their lives, their ideals are severely tested, as are their loyalties to one another. Chimamanda Ngozi Adichie brilliantly evokes the promise and the devastating disappointments that marked this time and place, bringing us one of the most powerful, dramatic, and intensely emotional pictures of modern Africa that we have ever had.
