[In this book, the authors] offer [an] account of the world's largest desert. They include a complex history (both natural and human), as well as a look at the complicated ethnology and present-day life of the various tribes (Tauregs, Berbers, Moors, and Tubu) that have adapted to this incredibly harsh climate.-Library Journal. [In the book, they] transform our image of the Sahara from that of a vast and forbiddingly desolate land to one that excites in its history, is awesome in the stark beauty of its ever-shifting and majestic landscapes, and is home to some of the world's most colorful and resilient nomadic peoples. [They also] cogently pointed up the ominous implications for the human future if we fail to heed its lessons.
