Blind descent (Little, Brown Book Group)

The deepest cave on earth was a prize that had remained unclaimed for centuries, long after every other ultimate discovery had been made. This is the story of the men and women who risked everything to find it, earning their place in history beside the likes of Peary, Amundsen, Hillary, and Armstrong.

In 2004, two great scientist-explorers attempted to find the bottom of the world. Bold, American Bill Stone was committed to the vast Cheve Cave, located in southern Mexico and deadly even żeby supercave standards.

On the other side of the globe, legendary Ukrainian explorer Alexander Klimchouk - Stone's opposite in temperament and style - had targeted Krubera, a freezing nightmare of a supercave in the Republic of Georgia.

"Blind Descent" explores both the brightest and darkest aspects of the timeless human urge to discover - to be first. It is also a thrilling epic about a pursuit that makes even extreme mountaineering and ocean exploration pale żeby comparison.

These supercavers spent months in multiple camps almost two vertical miles deep and many more miles from their caves' exits.They had to contend with thousand-foot drops, deadly flooded tunnels, raging whitewater rivers, monstrous waterfalls, mile-long belly crawls, and much more.

Perhaps even worse were the psychological horrors produced żeby weeks plunged into absolute, perpetual darkness, beyond all hope of rescue, including a particularly insidious derangement called "The Rapture".

"Blind Descent" is a testament to human survival and endurance - and to two extraordinary men whose relentless pursuit of greatness led them to heights of triumph and depths of tragedy neither could have imagined.
