This book is the story of six years that the authors devoted to the study of an iconic large cat, the cheetah. Their study area was the large, remote, and pristine Kgalagadi Transfrontier Park on the border of Botswana and South Africa.

Their aim here is to relate what they consider to be a fascinating story about the lives of these cats in a different habitat from the one most people associate the cheetah with – a sandy desert rather than a grassy plain. They hope to entertain and inform the reader with what they learnt about the daunting challenges cheetahs face, and the wonderful adaptations cheetahs have evolved to survive in the competitive world of natural selection.

The book is divided into five parts: Part One gives the background to this adventure; the why, when, where, who and how aspects. Part Two discusses the fundamental question of what cheetahs eat and how they go about obtaining their food; the fascinating evolutionary arms race between predator and prey, some of the behavioural, physiological, and ecological ramifications, as well as the relationships of cheetahs with the other carnivores. Part Three turns to social affairs; the way cheetahs distribute themselves in the landscape, the way they find and choose mates, and the trials and tribulations of raising a family. In Part Four, the authors switch to more personal and human matters; the challenges of living and working in an isolated and infrastructurally limited environment, and two chapters written by Margie: one on their experiences with the Bushmen, the other relating a selection of memorable incidents, not specifically related to the cheetah study. The final part addresses two practical topics; the first comparing how cheetahs have adapted to two different environments: the lush Serengeti plains and the arid Kalahari, the other giving the authors' perspective on cheetah conservation.

Hyenas have a bad reputation and are misunderstood by most people. Until recent years many wildlife publications used words like freak, stupid, demented and ungainly to describe hyenas, but in this title the author allow the reader to see these intriguing animals for what they really are: intelligent, powerful, even beautiful. Gus and Margie Mills, newly married, trekked to the Kalahari to spend two years studying the little-known brown hyena. They were so enchanted by these captivating animals that they ended up stayed for 12 years and uncovered a treasure trove of facts about the lives of both brown and spotted hyenas. Their studies allowed them to get to know the hyena clans and their hierarchies intimately and became privy to events which only a handful of people have ever had the privilege to witness.
