I have long been fascinated with the history of medieval France, bloody though it was. This book, the first in a trilogy, in particular, as it deals with the legendary holy grail and of the mystery surrounding it. The storyline interweaves a modern-day archaeological dig with flashbacks to the 13th Century. As the two threads converge, the reader is drawn more and more intimately into the emerging design of the intricate plot. The 'aha' moments are gratifying, and I truly appreciate the author's execution of the storyline.
