Cry Of The Kalahari by Mark Owens

"Carrying little more than a change of clothes and a pair of binoculars, two young Americans, Mark and Delia Owens, caught a plane to Africa, bought a thirdhand Land Rover, and drove deep into the Kalahari Desert. There they lived for seven years, in an unexplored area with no roads, no people, and no source of water for thousands of square miles. In this vast wilderness the Owenses began their zoology research, working alongside animals that had never before been exposed to humans. An international bestseller, CRY OF THE KALAHARI is the story of the Owenses' life with lions, brown hyenas, jackals, giraffes, and the many other creatures they came to know. It is also a gripping account of how they survived the dangers of living in one of the last and largest pristine areas on Earth." -- page 4 of cover.
