Young ex-novice Catherine LeVendeur is an independent spirit, fiercely loyal to both her faith and her family. Though the two sometimes conflict, with terrible consequences, her life remains committed to preserving what - and who - she loves.

But Catherine's loyalty is sorely tested when she and her family return to their French home to discover a Knight Templar has been brutally murdered inside: someone is threatening to reveal her closely held secret about her family's Jewish roots. But Catherine never wavers in her convictions, as she knows it falls to her to discover who would kill a soldier of God and why her family would be targeted in such a horrendous fashion.
