The mystic and legendary British explorer Colonel Percy Harrison Fawcett disappeared in the unknown and unexplored territory of Brazil’s Mato Grosso in 1925. For ten years he had wandered the forests and death-filled rivers in search of a fabled lost city. Finally, convinced that he had discovered the location, he set out for the last time with two companions, one of whom was his eldest son, to destination “Z,” never to be heard from again. This thrilling and mysterious account of Fawcett’s ten years of travels in deadly jungles and forests in search of a secret city was compiled by his younger son from manuscripts, letters, and logbooks. What happened to him after remains a mystery.
