When Claudia Drake has a vision her family has been kidnapped, she gets help from her grandmother's best friend. The friend calls in the Pendragon Alliance. Among others, they send Finn Pendragon, who reminds Claudia of a bear. But there's something interesting about the bear. He resonates with the same energy frequency as the ancient sword she has been protecting ever since her paternal aunt's death. He's connected somehow, but how exactly? When she discovers the bear, aka Finn, is the man to whom she's supposed to hand over her sword, it makes more sense.
Finn and Claudia set out with trusted friends to fulfill both of their duties. Duties set in place for them centuries ago. Duties that some do not want them to accomplish and will do whatever they can to stop them. Can they do what they need to before Morgause or the Vanir, Gwarthgydde, stop them?
