From the time he is a young boy, Neftalí hears the call of a mysterious voice. Even when the neighborhood children taunt him, and when his harsh, authoritarian father ridicules him, and when he doubts himself, Neftalí knows he cannot ignore the call. He listens and follows as it leads him under the canopy of the lush rain forest, into the fearsome sea, and through the persistent Chilean rain on an inspiring voyage of self-discovery that will transform his life and, ultimately, the world.
