A really fun book, well worth your time if you like Pratchett. None of our old pals [Rincewind, Gaspode, Vimes, Susan] put in an appearence [other than the guy WHO TALKS LIKE THIS and an old monk with a broom, and they but briefly], but it does add some info to the overall Discworld mythology, and provides some laughs as well.

Ex Output:
Positive

There is no other book on Africa, or Arabia, like this one! Like in his other books, Childress rambles from place to place looking for mysteries, lost cities, and adventure. If you are looking for some dry fossil hunter story, this isn't it. It's the only book that I know of that covers such unusual topics as port cities in the middle of the Arabian Desert, the history of the Ark of the Covenant, the giant megaliths of the Kalahari Desert and other little-discussed topics. Lots of old maps, photos and illustrations. It is a fun book to browse through as well.
