What this book is about

Three disparate storylines converge on a single moment: Edwin St. Andrew, exiled to Vancouver Island in 1912; Olive Llewellyn, a novelist in 2203 on her last book tour before a pandemic; and Gaspery-Jacques Roberts, a detective from a lunar colony investigating an anomaly that appears across centuries. Mandel's short, elegant novel—companion to Station Eleven and The Glass Hotel—meditates on time, art, pandemics, and the strange comfort of believing that everything that has happened will always have happened.
