As anyone interested in West Africa will know, finding information in English about Mauritania is pretty difficult. Even books like Lonely Planet's West Africa guidebook cover the whole country (which, don't forget, covers an area twice the size of Spain!) in about 30 pages. There are a number of quality French books about the country (check out "La Mauritanie d'Aujourd Hui" if you can read French), but that's all. So, when I heard about this book (an English original, not a translation from French!), and saw I could buy it for 1p from Amazon, I couldn't really refuse it!
As one would expect from a country also known as "The Great Void", there is not a great deal of action or excitement in this book. However, in no way could it be described as boring. As someone who is keen on this area, it was very interesting to read descriptions from a Western perspective on places that elsewhere are only mentioned by name, not actually discussed in great detail. Peter Hudson visits all the "major" towns in Mauritania - Nouakchott, Nouadhibou, Chinguetti etc - and his experiences varied greatly. We also get an insight into the views of the people he meets - their views on women, religion etc - that one wouldn't get from a mere travel guide.
One thing that was never made clear to me was why Hudson decided to go there in the first place. He travelled alone, and doesn't seem to be bound by any sort of timetable or schedule. There are few Westerners who could endure the primtive conditions and the poverty that he seems to relish in (never mind the heat!).
I would recommend this book to anyone interested in West Africa or, more specifically Mauritania itself, as it is a highly readable account of one man's travels there, and (as far as I am aware) the most in-depth book about this desolate country ever to be published.
