With his masterful and powerful style, and without ever losing his sense of humor, Lucas Landais delivers his vision of Raymond Maufrais' adventure.

1949. 23-year-old Raymond Maufrais has a slightly crazy dream: to travel from French Guiana to Brazil via the Tumuc-Humac mountains, then down the Rio Jary to Belém. On foot, and alone. The young man has already proven his courage, having joined the Resistance and a pacification campaign in Brazil. And yet... all that would remain of his expedition is a travel journal, miraculously discovered by an Amerindian. Published posthumously, this text is now celebrated by adventurers of all kinds.
