One winter in the mid-1970s, Dervla Murphy, her six-year-old daughter Rachel and Hallam, a hardy mule, walked into Baltistan close to Pakistan-held Kashmir—the frozen heart of the Western Himalayas. For three months they travelled along the perilous Indus Gorge and into nearby valleys, making a mockery of fear, trekking through the forbidding Karakoram mountains and lodging with the Balts, who farm one of the remotest regions on earth. Despite the hardship, Dervla never forgot the point of travel, retaining enthusiasm for her magnificent surroundings and using her sense of humour to bring out the best in her hosts, who were often locked into the melancholic mood of mid-winter. This hair-raising, quirky and vivid account of their adventure is a classic of travel writing.
