The 2010s were a hugely significant decade for the Booker, largely due to the shift in rules which came into place in 2014. From that year onwards, the Prize was open to all novels published in the English language, replacing the long-held (and many might say, dated) criteria that focused on authors of British, Irish and Commonwealth heritage. This shift led to a lot of hand-wringing and fretting about the potential “domination” of the Prize by US authors, and a dilution of what the Prize stood for.

Milkman is told in the distinctive voice of an unnamed 18-year-old "middle sister" trying to go about her life in an unnamed city in peak-Troubles Northern Ireland. She is stalked and harrassed by a 41-year-old paramilitary officer known only as "Milkman". False rumours spread that she is in a relationship with this character, affecting her relationship with her mother, the wider community, and her "maybe-boyfriend".
