Joseph Hobbs based his work on Leo Tregenza's earlier "Egyptian Years" (op) and updated and drew on Tregenza's accounts of life with the Bedu of the Eastern Desert of Egypt, between the Nile and the Red Sea.
Geographically, botanically, zoologically and anthropologically it is a fascinating book with all kinds of gems of information which are found nowhere else. It can be a little dry in places (no pun intended) hence the four stars rather than five but for those travelling in this arid, yet beautiful, region, it is well worth the effort.
