Book excerpt: Traveling through Peru, tracing the history of the Incas from their royal cities of Cusco and Machu Picchu to their mythic origin in Lake Titicaca, Ronald Wright explores a country of contrasts—between Spanish and Indian, past and present, coastal desert and mountainous interior. In his highly entertaining and perceptive account, Wright brings to life a complex culture, a land of ancient traditions seeking its place in the modern world. Embracing history, politics, anthropology, and literature, Cut Stones and Crossroadsis a fascinating travel memoir and the study of a civilization by a writer who has won international awards as both a novelist and a historian.
