Discuss Sea of Tranquility by Emily St. John Mandel.

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 an island off Vancouver in 1912 to a dark colony of 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 English 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 spare change in the echoing corridor of an airship terminal as the trees of a forest rise around him.
