4.0

I read this book for an environmental science course in grad school (and, to be honest, I probably would have enjoyed it more if I hadn't had to write a paper on it), but even with that it was a very good read with a compelling through line and characters.

Fascinating history that reads almost like a mystery novel in a very good way. I would recommend to most readers, as long as you have an interest in the science/history aspect of it.
