A chronicle of Nigeria in the turbulent 1960s, Chimamanda Ngozi Adichie’s novel Half of a Yellow Sun (2006) is, to put it crudely, a page-turner: a story of love, sex, betrayal, horror, heartbreak, and, ultimately, forgiveness. In other words, ideal material for cinema: it is easy to understand why this film adaptation has been described by its star Thandie Newton as a Nigerian Gone with the Wind.
