Half Of A Yellow Sun by Chimamanda Ngozi Adichie

Set during the Nigerian-Biafran War of the late 1960s, this powerful novel follows the intersecting lives of Olanna, her twin sister Kainene, intellectual Odenigbo, and British writer Richard. As ethnic tensions erupt into violence, their comfortable lifestyle collapses into severe war trauma, starvation, and grief. The narrative vividly explores the human cost of conflict, post-colonial politics, and complex emotional betrayals amidst a nation struggling for independence.
