If you like true adventure (not fiction), have a spot in your heart for nature, different cultures and personal hardships and challenges with a goal of self improvement and introspection, then this book should be in your personal library. If you don't have the above, you will probably find the text slow and boring, and put the book down before the half way mark.
The author goes into some detail that is minutia, irrelevant, and tedious, and then all of a sudden, you find yourself re-reading the same few sentences several times in order to fully grasp the magnitude of what he just said. Amongst all the sand that he describes in the book, he'll also provide golden nuggets of insight into the human soul and spirit, and done so very elequently, just like an Oasis in the midst of a bleak desert. That is to say, it's worth the effort to get there.
This is not a book with a "plot". It's a personal account of an individuals travels with the Bedu. You can read into it Protagonists and Antagonists, but again, this is not a fictional work. Nonethless, you find yourself rooting for "Umbarak", as the author is called, and worrying about other Arabs who would kill him given the chance, and there are many chances and near misses.
Surprisingly, there are also bits and pieces of insight into the Arab world that help put into perspective some of the tensions we see today in the Middle East. While that is certainly not his intentions, he does touch on some things that are relevant today in respect to the Muslim attitudes towards Christians and Jews.
This is not a book that can be glossed over and read during TV commercials, on the bus, or while the kids are screaming up and down the hallways... you need to focus and concentrate, and if your heart yearns for nature and adventure, you'll find it well worth the effort.
