"From the #1 bestselling author of the Scotiabank Giller Prize-shortlisted The Glass Hotel and the internationally bestselling Station Eleven comes a new novel of dazzling imagination. In this captivating new novel of imagination and ambition, a seemingly disparate array of people -- 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 actual pandemic, a resident of a moon colony almost 300 years in the future, and a lonely girl who videos an old growth forest and experiences a disruption in the recording – come into contact with a time traveller who must resist the pull to change the past and future. Blurring the lines between reality and imagination, Emily St. John’s dazzling new novel 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."--Provided by publisher.
