In this unnamed city, to be interesting is dangerous. Middle sister, our protagonist, is busy attempting to keep her mother from discovering her maybe-boyfriend and to keep everyone in the dark about her encounter with Milkman.
But when first brother-in-law sniffs out her struggle and rumours start to swell, middle sister becomes "interesting" — the last thing she ever wanted to be. To be interesting is to be noticed, and to be noticed is dangerous. Milkman is a tale of gossip and hearsay, silence and deliberate deafness. It is a story of inaction with enormous consequences.
