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 bestselling 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. When Gaspery Roberts, a hotel 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 time line of the universe. A virtuoso performance.
