Blind Descent: The Quest to Discover the Deepest Place on Earth

I'm about a third of the way through this book (in about one night, mind you). So far, it's quite an interesting read chronicling the exploits of extreme cave exploration, one of the last great unexplored territories. And seemingly far more dangerous than the exploration of the oceans, space, mountains, etc. This book covers the perils and pitfalls, as well as some of the spectacular beauty, solitude and other things encountered by extreme cave explorers. There are deaths, marriages, divorces, mutinies, and more. I'd say this book will appeal to a pretty wide audience. There's a little bit for everyone, and it just seems quite fascinating. Likely it will only get better, since I've only read about one of the two "big name" cave explorers and have yet to delve into the story of the other (which occupies the latter half of the book). Both explorers were involved in quests to discover the "deepest cave" in the world. Somewhat literally "the bottom of the world." I'll give this one a thumbs up, for sure.
