A novel in which a character undertakes, with sensibility and intelligence, a voyage around the world, and becomes enlightened as to the abyss and splendors of human relations, sex, friendship, philosophy and history. Percusión advances like the exercising of a memory interwoven in a great game with temporality and with some of the social and individual milestones of contemporary history.
