One of the Best Books of the Year: The New York Times , NPR, GoodReads “One of [Mandel’s] finest novels and one of her most satisfying forays into the arena of speculative fiction yet.” — The New York Times 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 best-selling 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 black-skied 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.","forthcoming":false,"isbn13":"9780593466735","publication_date":"20230328","publisher":"Knopf Doubleday Publishing Group","slug":"sea-of-tranquility","subtitle":"A Novel","title":"Sea of
