Query: A Sham

A badly written hoax by someone who never actually lived with the Yanomami, this book features the convoluted adventures of a woman who decides to live in a community of Brazilian Indians. To those familiar with the Yanomami (I lived with them for 5 years) this is obvious fakery, although my edition of the book did not claim that the book was "a true story" or "nonfiction". Among other clues: she describes a Yanomami wedding ceremony--when in fact no such ceremony exists among the Yanomami, a fact you might know if you had read one or two of the many ethnographies on this tribe.
