Chosen for Simon Mayo's Radio 2 Book Club, this is the chilling new ghost story from the bestselling author of Dark Matter.

The Himalayas, 1935.

Kangchenjunga. Third-highest peak on earth. Greatest killer of them all.

Five Englishmen set off from Darjeeling, determined to conquer the sacred summit. But courage can only take them so far - and the mountain is not their only foe.

As the wind dies, the dread grows. Mountain sickness. The horrors of extreme altitude. A past that will not stay buried.

And sometimes, the truth does not set you free.
