Time, memory, and human connection ripple across centuries in Sea of Tranquility, a novel by Canadian author Emily St. John Mandel. This haunting and intricately woven novel of pandemics, temporal anomalies, and the fragile threads that connect us traverses continents and centuries—from a remote forest in 1912 British Columbia to a lunar colony in the 2400s—drawing seemingly disparate lives into a single, resonant narrative. At its heart is a mysterious anomaly in time, one that echoes through generations and offers a meditation on the nature of existence and the illusion of permanence.
