1291 Saint-Jean d'Acre is a great defeat for the knights of the temple, however, some massacre survivors escape with an object that can upset humanity. XXI century, four horsemen dressed as Templar penetrate the Metropolitan Museum in New York, is accagent everything and steal various objects on loan from the Vatican. Tess archaeologist who attends the exhibition notices a fake Templars seize an object in speaking Latin. After the carnage sending the FBI agent Sean Reilly investigate. He meets Tess air to know certain things and it will be driven in a chase that will lead him far from the United States. I loved this novel for the next plot, suspense, adventure (it goes 100 mph) and it's exciting. Moreover it is well written. By cons I did not like the mystical side which from the "Da Vinci Code" is the goodwill of a lot of authors, although in 2008 the fashion seems to falter. This book is like reading a good thriller and it is already very good.
