I read "Running the Amazon" because my wife and I were participating in a cruise on the Amazon and an additional two days at the Explorama Lodge, all of our trip at the Peru end of the Amazon, basically in the Iquitos area. Also, my reading tendencies lean toward adventure descriptions, so "Running the Amazon" looked like a book I would finish.
It was so much more than an adventure book, although it certainly was that. - This is a personal description of the first expedition to begin in the snowfields of the Andes, at the continental divide, where the first trickle originates, all the way to the Atlantic - 4200 miles. I can imagine, well almost, how treacherous the white water must have been coming out of the Andes, based on how much water we saw flowing down the Amazon even at the junction of its two major tributaries in Peru where the river officially begins.
The majority of "Running the Amazon" takes place in Peru (even though in total miles the majority of the trip is in Brazil). I would estimate that 50% of the text is about the history of the area, mostly Peru, and the culture, past and present. Also, the author is pretty funny - intentionally or not - in how he describes the adventures of he and his colleagues. I have always wondered about the revolutionary group, Shining Path, and since the book is set in the late 1980s, a good description of the group and its history is provided.
Since Joe Kane is not a man who apparently had been a kayaker, or at least anything approaching a serious kayaker, prior to his journey, it makes his adventures more interesting to the average reader like myself, and this is true also for his descriptions of interpersonal difficulties among some of the expedition.
Because "Running the Amazon" is so well written, and so readable, I am going to read Mr. Kane's other book about the area, "Savages," which describes the difficulties of a group of Ecuadoran people with modern culture. I highly recommend "Running the Amazon."
