This is a very clear and balanced discussion of the events surrounding 9/11 and the problems with the "received account". The author is an eminent theologian and philosopher of religion. He examines the evidence in a scholarly way and offers copious sources and footnotes, so virtually every statement of fact and quotation is referenced.

The question of what happened on September 11th 2001 is by far the most important issue in the world today, in comparison with which everything else pales into insignificance. This book is one of the best sources available for trying to understand that question.
