Twelve novels are in contention for the £25,000 prize, with settings spanning the globe and the centuries: from ancient Tahiti to Australia and Tasmania at the dawn of colonisation; from seventeenth-century Massachusetts to the 19th century literary salons of Europe; from the shores of Suffolk to the quiet countryside of Thomas Hardy’s Dorset; from the gold-rush-giddy American south to Belfast under siege during the Blitz; and from the cramped streets of 18thcentury London to the sogginess of an Irish bog in the 1950s.
