An incredibly compelling novel of art, time, love and plague that takes the reader from Vancouver Island in 1912 to a dark colony on the moon three hundred years later, unfurling a story of humanity across centuries and space. Sea of Tranquility is a novel that investigates the idea of parallel worlds and possibilities, that plays with the very line along which time should run. From the award-winning, bestselling author of "Station Eleven" and "The Glass Hotel".
