What compels mountain climbers to take the risks that they do? Is it the thrill in the physical accomplishment, in managing to defy the odds, or both - and why do they continue to do what they do in the face of such great danger? In On the Ridge Between Life and Death, David Roberts confronts these questions head-on as he recounts the exhilarating highs and desperate lows of his climbing career.

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he's alive - and even if he could get word out, his supplies would be gone long before a rescue could arrive. Chances are, though, he won't have time to starve to death. The damaged machinery, unforgiving environment, or plainold "human error" are much more likely to kill him first.
