From Vancouver Island in 1912 to a dark colony of the moon three hundred years later. The Sunday Times bestseller, Sea of Tranquility by Emily St. John Mandel is a story of parallel worlds and possibilities that plays with the very line along which time should run.

An exiled Englishman, a writer trapped far from home, and a girl destined to die too young, have each glimpsed a world that is not their own. Travelling through the centuries, between colonies on the moon and an ever-changing Earth, together their lives will solve a mystery that will make you question everything you thought you knew to be true. From the award-winning author of Station Eleven.
