A man dips a madeleine into a cup of tea and the past comes flooding back with such force that it takes seven volumes and four thousand pages to contain what follows. Proust spent the last decade of his life writing from a cork-lined room, building a cathedral of memory in which time is not a line but a substance that can be recovered, held, and understood. The first volume was rejected by every publisher and self-published in 1913 to scornful reviews. He did not live to see the final volumes in print. What he left behind is the longest novel ever written and, by the testimony of nearly everyone who has survived it, among the most life-altering: a work in which the true self is revealed not through thought but through sensation, in privileged moments when time collapses and something eternal briefly surfaces.
