The stories were written for intelligent middle school children, who have a sense of sophisticated humor and who like adventure. There are elements of surprise and adventure with much scientific materials, some of which is true and some not true. The reader should be motivated to find out for themselves. For example, (1) there was certainly a massive eruption in Krakatoa (the survival of the Viven beetle is entirely fictitious) and (2) there is a Yucca plant pollinated by a moth.

This is a story of an almost vanished Africa; a world of myth and magic in which the indigenous peoples of the continent lived for uncountable centuries before the Europeans came to shatter it. The main character is a boy who has a relationship with this Africa not unlike Kipling's Kim with the antique world of India. François Joubert, whose Huguenot ancestors settled in Africa three hundred years ago, lives as a solitary child on his father's farm. 'Hunter's Drift'. Here, in the far interior of Africa, he experiences the wonder and mystery of an ageless, natural primitive life, his perception of it heightened by the influence of three people in particular - his Bushman nurse, the head herdsman of the local Matabele clan (his father's chosen partners in the pioneering of Hunter's Drift), and a hunter of legendary fame, now the chief ranger of a vast game reserve nearby. François' meeting with an untamed Bushman, Xhabbo, whose intuitive teaching nourishes his spirit; his strange pilgrimage to the distant krall of a powerful witch-doctor; his dramatic encounter and relationship with the daughter of a retired colonial governor; all are examples of African point and European counterpoint, in a highly original theme, moving to a strangely presaged and omened climax.
