When parishioners are burned to death in a German cathedral, the U.S. sends in the SIGMA force. The team discovers someone has stolen the priceless treasure stored in the cathedral's golden reliquary: the bones of the biblical Magi.
This is an intense, mystery/thriller adventure similar in style to Dan Brown's books. I read it for the themed reading challenge - my theme being books with the word bone/bones in the title. It's a page-turner, very interesting and a fun read. I will be looking forward to more books written by Rollins.
