In this controversial book, Stoll concludes that Rigoberta Menchu, winner of the 1992 Nobel Peace Prize, did not actually experience many of the events of her famous autobiography. Menchu herself has lately said that her account of peasant life and revolution in Guatemala articulates a collective --rather than a strictly personal -- experience, but here Stoll takes her to task for deluding the international community. It's an irritating, important book that will outrage fans of I, Rigoberta Menchu; detractors will feel vindicated.  (GML09, $25.00)
