Are you booked on one of our Namibia trips?  Or are you still deciding whether you should book on one of our Namibia trips?  Either way we can heartily recommend you read The Sheltering Desert by Henno Martin.  This fantastic travel/adventure book was written in 1957 about two German scientists who escape into the famed Namib Desert to avoid incarceration into the Germany Army at the start of WWII.
 
They survive in a landscape of harsh beauty and danger.  They become highly attuned to the thoughts, emotions and habits of the animals around them.  For the reader armed with a map of Namibia, it's a total immersion into a place where some of the oldest humans have existed.
