Cape Cod resident Willow McCord receives a package in the mail from Newcastle upon Tyne, England. In it is an intricately carved brooch in the shape of a sapphire blue feather mounted on a Celtic Cross. Suddenly, her life plunges into a whirlwind of motion in which events from her past dictate her future and drag her into a world of danger, mystery and spirituality.
Sawyer Hawksworth is connected to Willow through their joint ancestors. Sawyer has sought Willow out in order to fulfill a destiny left to them many generations earlier. Between past and present, Willow and Sawyer must battle the forces of evil in order to protect the world, while facing the growing attraction between them.
Can Sawyer make Willow understand how important the task at hand is to their futures? And will Willow be able to see beyond skepticism long enough to accept Sawyer for what she is? Will their love make them strong enough to win the battle?
