This is the third book written by scientists Mark and Delia Owens that I have read. I read the first when I went to Zambia, which is where they did a lot of their research and work with elephants to try and end the horrific poaching that was such a problem in Zambia. I really enjoyed this series, although I think those two did some incredibly crazy stuff that I could never have done because I am just not enough of a risk taker. The great thing is that their work really made a tremendous difference, both for animals and people in Zambia, and I was really impressed by the great lengths they went to to make such an important difference.
I am reminded of a quote from Margaret Mead that these two definitely practice:
"Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has."
