This was a fun books to read.
Not the first by this author that I have read, Sy's ability to describe locations, scenes, people and experiences are a big plus in all her books. In this one the four (or was it five? Not sure) trips to the Amazon river in pursuit of the Pink Dolphins are brought vividly and charmingly to life. The Amazon river the amazing jungles and all the inhabitants, residents and travelers make this an engrossing read.
Now as to the title animal; the pink dolphin, Inia geoffrensis, this book is allegedly about them, to a certain extent it is because they are an ongoing theme. But Sy's original plan to trace their migration in the fascinating rivers and flooded lakes of the Amazon stalled early when she found out they did not migrate. The people studying them gave her a LOT of assistance by the sound of it, but, in the end, she was trying to write a book about a not very visible, not very well studied Dolphin that lives in a river full of piranhas, which makes studying them that much more difficult. The rivers are not clear, there is/was not much scientific knowledge about them -I don't know if that has changed- this was published in 2000.
So rather than a narrow focus on one species, this book becomes a story of the Amazon: there are local myths told about the dolphins by locals; apparently they transform into beautiful young people and come ashore to seduce people, and more! There are interesting stories about the people who live there, the conversations efforts, the river itself, the people she meets, there is geology paleontology, staggering beautiful descriptions of a part of the world I have never been, but would not love to visit.
The Amazon comes across as lush, dangerous and intoxicating. I really admire what the author managed to do with this book because it can't have been easy but it has ended up a delightful read for the armchair traveler.
The writing is nice, at times it has shadows of the 'new age-ish' attitudes of the nineties that can be a bit embarrassing, and it gets a bit over enthusiastic with its religious overtones once or twice, but it is a christian country, so that is probably just an accurate reflection of the surrounds.
In general though, wonderful book. I know a lot more about the pink dolphins, river dolphins in general and the Amazon and it is definitely written for popular consumption, you need no scientific background at all to enjoy this lovely story.
