I was sorry to see that there were so few reviews. I started reading COAL and could not stop. The only thing I am going to say is that I wish everyone concerned with our planet would read this book. Ms Freese combined history and the human story in such a way that the story became a powerful integration of facts and emotions displayed against the background of historical events that would or could be dry and unappealing.We are all guardians of this planet and as such should at least have the facts (enough) to make informed decisions.
