The compelling story of 30-year-old climber Tom Ballard who disappeared on one of the Himalayas’ most deadly mountains, Nanga Parbat, in February 2019. Tom was the son of mountaineer Alison Hargreaves, who perished on K2 in 1995. Mother and son, two of the greatest climbers of all time, died at almost the same age in neighbouring mountain ranges, both doing what they loved best. They now lie forever encased in the ice of two of the world’s highest mountains. Left behind to cope with the enduring tragedy are Tom’s sister, Kate, and their father, Jim.
