Query: An explorer's musings

I confess to being quite a Hanbury-Tenison fan. Now nearing 70, the Royal Geographical Society-honoured explorer and conservationist decided to follow in some famous footsteps by spending 40 days in the desert (the Sahara, in this case). The book has 40 mostly short chapters, one for each day of his sojourn, in which the author muses on his life and gives us various vignettes of life among the Tuareg. The book is necessarily episodic and may be most appreciated by readers who are already familiar with some of the author's earlier books, especially his autobiography, "Worlds Apart". But if you enjoy literate and thoughtful non-fiction and haven't read Hanbury-Tenison before, this may whet your appetite for some of his other work. As always, Hanbury-Tenison is a voice of common-sense in our troubled world.
