Adichie tells an incredible story of how the Nigerian government and population persecuted and massacred it's own people of the Igbo tribe in the late 1960's.
Told from the perspective of a handful of different characters, the tale follows their individual stories as their lives are torn apart. Their beliefs and values are pushed to breaking point as they struggle to stay alive in a country that doesn't want them and a world that doesn't want to acknowledge they exist.
The stark contrast between life before and after the Nigerian/Igbo civil war, which is beautifully portrayed by Adichie, really emphasises the sense that it is all some horrible nightmare which couldn't possibly be true except that loved ones keep disappearing and dying. For me, more than any other character the story of Ugwu the houseboy embodies this sense of unreality, the impossibility that this good man can do such bad things.
Do read it, and do bear with it. If you enjoyed Achmat Dangor's book Bitter Fruit you'll enjoy this.
