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.

The Narrow Road to the Deep North tells the story of Dorrigo Evans, a famed war veteran and public figure in his later years, who considers his accolades to be unjustly earned. The novel reflects on major moments in his life, most centrally his role in the Australian Imperial Force during World War II and his regiment's internment as hard labourers on the notorious Burma Death Railway. In this period he is reluctantly installed as the commander of his regiment in the camp, and is forced into making numerous impossible choices that will inevitably lead to the death of his comrades. Against this is a constant thread focusing on his obsession with his brief affair with his uncle's wife, Amy, prior to the war, and his ongoing post-war infidelities to his wife and mother of his children, Ella.
