In this spellbinding chronicle, Greg Child takes us step by nerve-shattering step through the world's most remote regions
- as he cracks the death zone above 26, 000 feet, & attacks by fair means the world's most perilous pinnacles. From Child's assault on Gasherbrum IV to a season of tragedy & carnage on K2, Thin Air is more than one man's story
- it is an intimate portrait of mountains & those who climb them: what bonds clients together & what separates them, & what the mountains teach us all about life -- & death...

In 1997 Andy Cave climbed the north face of Changabang in the Himalayas & attained something most climbers dream of but at a huge cost: the harrowing process claimed the life of his friend & climbing partner. This trauma prompted him to examine his relationship with the mountains & confront the question of whether he would ever have the courage to face such a challenge on them again. Thin White Line tracks Cave as he tackles some of the severest challenges that modern Alpinism holds in an attempt to steel his resolve & find his answers.
