Edwin St. Andrew is 18 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 Canadian wilderness and suddenly hears the notes of a violin echoing in an airship terminal. Two centuries later, Olive Llewellyn is on a book tour. She’s traveling all over Earth, but her home is the second moon colony. 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 black-skied Night City, is hired to investigate an anomaly in the North American wilderness, he uncovers a series of lives upended.
