NEW YORK TIMES BESTSELLER NATIONAL BESTSELLER "One of [Mandel's] finest novels and one of her most satisfying forays into the arena of speculative fiction yet." --The New York Times "Mandel's sensational sixth novel offers immense pleasures of puzzle box plotting and high-flying imagination. . . . Masterfully plotted and deeply moving, this visionary novel folds back on itself like a hall of mirrors to explore just what connects us to one another, and how many extraordinary contingencies bring us to each ordinary day of our lives." --Esquire From the acclaimed, bestselling author of Station Eleven and The Glass Hotel, a "bold and exciting" (The Economist) and "transcendent" (Wall Street Journal) novel filled with "puncturing emotional truths" (Glamour) In this captivating tale of imagination and ambition, a seemingly disparate array of people come into contact with a time traveller who must resist the pull to change the past and the future. The cast includes a British exile on the west coast of Canada in the early 1900s; the author of a bestselling novel about a fictional pandemic who embarks on a galaxy-spanning book tour during the outbreak of an actual pandemic; a resident of a moon colony almost 300 years in the future; and a lonely girl who films an old-growth forest and experiences a disruption in the recording. Blurring the lines between reality and fantasy, Emily St. John Mandel's dazzling story follows these engrossing characters across space and time as their lives ultimately intersect. Sea of Tranquility is a breathtaking and wondrous examination of the ties that bind us together, by a master storyteller.
