Query: Want to understand more about Sept. 11? Read this book!

Actually, I would recommend reading Otis' The Twilight Labyrinth first, which gives the background on the roots of spiritual darkness, then read The Last of the Giants.Both books were invaluable in helping me understand the true causes of the turmoil in Central Asia and the thinking that led to the events of September 11, 2001.I can't give the book 5 stars for a couple of reasons. First, at times, Otis is not easy to read. Better editing would have helped. Secondly, Otis mentions the dangers of materialism in American society, but fails to elaborate much on this topic. Since materialism seems to be one of the reasons Muslims are so offended by the West, more information on the spiritual implications of materialism and consumerism would have added to the value of this book.
