This is a decent book because I love anthropology, ethnobotony, and learning about the Bushman. The beginning of this book was great, the author discusses how he and his group fall upon a thirsty group of Bushman. That part is great because it describes the interactions between the author and the Bushman. One of the author's mate on the trip, Dabe, a Bushman himself, also offers amazing commentary when they run into the Bushman.
However, in the middle, who knows what is going on. And the end was so confusing, but sorta okay. Van der Post discusses Bushman creation tales which are good in themselves because most books overlook the spiritual aspect of the Bushman--but the tales need more explanation--Van der Post talks over your head and says things don't need an explanation when they really do.
I would recommend reading 'Nisa, The Life and Words of a !Kung Woman' and 'The Harmless People' which both can be purchased online here!
