If you are the kind of traveller who embraces the adventurous, this astonishingly detailed and authoritative route and planning guide to one of the most staggering possible destinations will be right up your street. When so much of the world is at our fingertips, with the undiscovered shrinking day by day, the Sahara Desert is still one of the most mysterious wildernesses on the planet. The popular image provided by movies like Lawrence Of Arabia or The English Patient is of shimmering oases and photogenic dunes. But Chris Scott, while taking on board the fond perceptions of the Sahara most of us have, ensures thatSahara Overlandis a clear-eyed guide to what could be the adventure of a lifetime. (Although it has to be said that this is a trip for travellers with backbone: those who like a laid-back holiday need not apply).
