I have loved her Deryni series and was excited to see this (Book 1 in a series). But I found it very slow moving. Perhaps I needed to brush up on my Crusader history – and in fact I did so, to see what background facts were true.
I found it slow, and didn’t finish it. It tries to blend action in Crusader times, as the Crusaders are being pushed back, with a deeper evil. So the Knights are to defend the faith and within the Order is a secret society charged with protecting relics and stopping demonic activity. There appears to be ‘magic’ coming somewhere in the story, but I read about halfway and gave up, which I rarely do with a book.
