Sea of Tranquility by Emily St Mandel

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.
