"One River" is one of the most fascinating and readable books about South America that I have ever come across. Although Wade Davis obviously intends his work to be a tribute to his mentor, Schultes, and his friend Tim Plowman, the book is much more than a mere botanical biography. Davis writes with great enthusiasm and combines subjects that continually entertain and inform the reader. The book is filled with true tales of adventures on the Amazon, encounters with jungle tribes, fanatical hunts for rare plants, and wild journeys through the remote Andes. Exploration, excitement and ethnobotany are skilfully blended with a well-researched history of South America. The reader is presented with a great deal of thought-provoking material about the past, present and future of this contradictory continent. HIGHLY recommended.
