After being abruptly separated from Nicolas le Breton during the battle to save Mont Saint Michel from the English siege in 1424, Katelyn Michaels finds herself back in her normal twenty-first century life as an American teenager. Depressed and anxious to be reunited with Nicolas, she is comforted when a series of events and impressions lead her to believe she is being prepared for another mission as a Watchman.

After her beloved mentor, Jean le Vieux, comes to her in a dream and gives her the injunction to “Learn of the Maiden and take her the sword,” Katelyn understands that her mission involves assisting one of the most iconic figures in all of French History.

Katelyn is once again whisked back to the turmoil of medieval France during the Hundred Years’ War and to Nicolas. However, before the two can consider the future of their relationship, they must first complete their mission to take the sword to the Maiden. Little do they know that their old nemesis, Abdon, is already on their trail and will do everything in his unhallowed power to stop them.
