Emily St. John Mandel weaves another genre-bending, thought-provoking tale with "Sea of Tranquility." In this slightly fantastical novel, three people from three different times and places find their stories irrevocably entwined. A young man in early-twentieth-century Vancouver, an author born on a moon colony, and a detective with a troubled past all are connected by one strange experience: the sound of a violin, playing in an unexpected place. Bound together by this anomaly, the characters strive to understand what is happening to them. When the detective discovers that time travel is involved, their stories take an even more unexpected turn.
