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 Luminaries takes us to New Zealand, during the Gold Rush years in the mid Nineteenth Century. In straightforward plot terms, it’s a mystery novel centering on the aftermath of a series of seemingly disconnected events in the town of Hokitika. Central is the death of a little-known hermit, Crosbie Wells, alongside the disappearance of a rich young prospector, Emery Staines, and the arrest of opiate-addicted prostitute Anna Wetherell.
