The award-winning， best-selling author of Station Eleven and The Glass Hotel returns with a 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。

Edwin St。 Andrew is eighteen years old when he crosses the Atlantic by steamship， exiled from polite society following an ill-conceived diatribe at a dinner party。 He enters the forest， spellbound by the beauty of the Canadian wilderness， and suddenly hears the notes of a violin echoing in an airship terminal--an experience that shocks him to his core。

Two centuries later a famous writer named Olive Llewellyn is on a book tour。 She's traveling all over Earth， but her home is the second moon colony， a place of white stone， spired towers， and artificial beauty。 Within the text of Olive's bestselling pandemic novel lies a strange passage: a man plays his violin for change in the echoing corridor of an airship terminal as the trees of a forest rise around him。

When Gaspery-Jacques Roberts， a detective in the Night City， is hired to investigate an anomaly in the North American wilderness， he uncovers a series of lives upended: The exiled son of an earl driven to madness， a writer trapped far from home as a pandemic ravages Earth， and a childhood friend from the Night City who， like Gaspery himself， has glimpsed the chance to do something extraordinary that will disrupt the timeline of the universe。

A virtuoso performance that is as human and tender as it is intellectually playful， Sea of Tranquility is a novel of time travel and metaphysics that precisely captures the reality of our current moment。
