So why would three Britons with ‘a PhD, two Oxbridge degrees and a batch of Masters degrees’ between them, undertake a 2,500-mile journey in a 25-year-old Land-Rover across this menacing land? This was a return from an African tour, so in fact it is the story of getting home. The idea of ‘discovery’ is central to the narrative, partly in understanding a little-known land, but also as ‘an exploration of our personal limits and the depths of our convictions’.
