In a major suspense novel set to surpass the internationally bestselling An Instance of the Fingerpost comes a dazzling story of youth, love and murderous ambition--a novel of time travel spanning three beautifully detailed worlds: the intellectual spires of Oxford in 1960, an ancient Arcadian world, and a dystopian future.In 1960, Henry Lytten is an Oxford don who dabbles in espionage and fiction writing. Rosie Wilson is the quick-witted, curious 15-year-old girl who feeds Professor Lytten's cat. Several hundred years in the future, living in a dystopian society on the Isle of Mull, is Angela Meerson--a brilliant psychomathematician who has discovered the world-changing potential of a powerful new machine. Somewhere, sometime, is Jay--a scholar's apprentice in an idyllic, pastoral land. Who these people really are, and how their stories come together, will be revealed in Iain Pears's fascinating great puzzle of a novel.From the Hardcover edition.
