Solomon's Seal - An Ogmios Short Novel — Steven Savile; Steve Lockley

With the discovery of the long lost Seal--real or not, it doesn't matter, the implications for the West are the same--Konstantin and Orla find themselves in Jerusalem and Palestine fighting for their lives in a desperate race to stop all hell breaking lose. They don't know who they can trust. They don't know which way to turn next. All they know is they have to find the Seal and divert the detonation of a dirty bomb at one of Jerusalem's most holy sights in the process.
