Apsley Cherry-Garrard (1886-1959) was one of the youngest members of Captain Scott's final expedition to the Antarctic. Cherry undertook an epic journey in the Antarctic winter to collect the eggs of the Emperor penguin. The temperature fell to seventy below, it was dark all the time, his teeth shattered in the cold and the tent blew away. 'But we kept our tempers,' Cherry wrote, 'even with God.'

After serving in the First War Cherry was invalided home, and with the zealous encouragement of his neighbour Bernard Shaw he wrote a masterpiece. In The Worst Journey in the World Cherry transformed tragedy and grief into something fine. But as the years unravelled he faced a terrible struggle against depression, breakdown and despair, haunted by the possibility that he could have saved Scott and his companions.

This is the first biography of Cherry. Sara Wheeler, who has travelled extensively in the Antarctic, has had unrestricted access to new material and the full co-operation of Cherry's family.
