Chimamanda Ngozi Adichie
Fourth Estate, 400pp, £20
In the interests of full disclosure: I am wary – an acquired wariness; all tastes are acquired – of the novel as platform. Legitimately, editorials are platforms, opinion pieces are platforms, blogs are platforms. But fiction that announces its debate too loudly risks simplification. “Subtle”, “complex” and “nuanced” are almost always positive critical terms.
