Finished this book today.
I'm not familiar with energy sector at all and have never invested in oil/gas companies so reading this book gave me some very good insight. I got the same feeling as well that these guys are pretty much gamblers and there is a significant risk of these companies getting bust. I especially enjoyed the parts about Aubrey McClendon and Tom Ward, as I didn't know anything about them before this book. Although reading this book confirmed me that investing in O&G companies isn't my thing, it will be interesting to see what happens with some of the companies portrayed in this book going forward.
