I finished this yesterday evening and I have to say for a book that was over 500 pages with 180 pages of endnotes I was disappointed. It‘s a 9/11 behind the scenes story - events that led up to the day, however the book abruptly ends on July 9, 2001. And much of the book hinges around a conspiracy theory - that key US sources were aware of the attack and did nothing as a way to enter the war in Afghanistan. Not buying that!!!
