No Way Down is the the gripping, terrifying story of a brutal struggle for survival on the upper slopes of the Himalayan K2, the world's most hostile terrain, by Graham Bowley.

K2, August 1st, 2008.

Thirty climbers are attempting the summit of the most savage mountain on Earth. They make it. But before they start their descent an ice shelf collapses, sweeping away their ropes. It is dark. Their lines are gone. They are low on oxygen. And it is getting very, very cold.

How many will make it down alive?
