Julio Cortázar, long and lean, raven-haired, horn-rimmed glasses, the countenance of the eternal adolescent, and indomitable. One of the most acclaimed and best-loved contemporary writers, and one of the indispensable names of the Latin American Boom. This illustrated biography allows us to traverse, in the hands of Jesús Marchamalo and Marc Torices, the most relevant episodes of Cortázar’s life and to learn, as privileged witnesses, a large of his world and his literature: his reading and travels, his childhood, his friends, his first writings, jazz, Paris, his strolls with Maga, and his love of cats. This is an indispensable portrait of the author of Rayuela (Hopscotch), full of understanding and admiration. Never had we seen him in this way.
