Query: Clunky writing, sloppy research

Sadly, this book is very poorly done. Historical "facts" are inaccurate, for example, maintaining that Paul was a Gentile and the Knights Hospitaller were never a military order. The dialogue is so painfully clunky that a reader really has to force his way through the murk. I gave up at about halfway through, and I'm a very patient reader. I cannot recommend the book to anyone.
