Even though Fidel Castro founded the "26 of July" movement, this book shows that the organizing throughout Cuba fell on the shoulders of an underground leader named Frank Pais, who was also responsible for the survival of the incipient guerrilla force led by Castro in the Sierra Maestra. Pais became not only the National Chief of Action-as portrayed in the official publications-but the top leader of the M-26-7's National Directorate. The antagonism between Castro and Pais may have been the reason for his mysterious death when he was only 22 years of age. This is the true story of his life and legacy. At this crucial time, when historians are trying to arrive at the revolution's final balance, a book like this is essential to read before reaching an impartial verdict.
