A great history of Islam told by one who knows all the man-made changes of the essential tenets of this religion. Again, what began as pure and tolerant monotheism evolved into the fractions, factions, and fanatics in today's world. Just like every other "religion" on the planet.
It should be required "reading" for every thinking person who cares about other people in today's world to separate fact from fiction about a little understood and much maligned organized religion.
I own the book as well, and it helped to refer to it during my listen. Unless one is fluent in Arabic, the names, places, and phrases used through out the book confuse the western ear. Being able to read them, flip through the pages to sort out some confusion as to who did what to whom, and/or why helped a lot.
