Sea of Tranquility by Emily St. John Mandel
A story that moves from 1912 Vancouver Island to a moon colony 300 years later, following characters connected by a strange moment in time. An exiled young man hears a mysterious violin in the forest, and centuries later a famous writer includes the same scene in her novel. When a detective investigates this strange anomaly, he discovers how several lives across different eras are linked—and how one extraordinary choice could change the entire timeline.
