Seems too cliché. Too much like a Derynii book but simply with the Templers.

Arnault de Saint Clair is a Knight Templar and a member of the Circle--the esoteric inner group with magical connections. He has a protege, Torquil Lennox, a Scots Templar. Together they get involved in Scotland's struggle for freedom from England. In the process, they fight dark magic as well. Protecting the Stone of Scone, they revitalize it using William Wallace as a sacrifice--the Uncrowned King. Robert the Bruce is crowned king at the end. Scotland also looks to be a place of Templar refuge--the Fifth Temple--as things are getting dicey in France.

It was ok to good.
