It's good for those who like such kind of books. An events described are a bit monotone and the story is mostly focused on a geographic facts - unfortunately. The author is has a low opinion about locals I'd say. He mostly give a vivid pictures of cunning, lazy, greedy, cruel and unintelligent people. His attitude to a slavery is also rather polite, with a thin trace of judgement. However descriptions of local people, their behavior, customs and attitude are quite interesting. Still I'd expect more stories about people and places author has met during his travel.
