In this powerful conclusion of the Darkest Age trilogy, the ancient god Loki has been set free from the chains that have bound him for centuries. As Edmund and Elspeth desperately search for him, the fire and destruction they expect to find is nowhere to be seen. They discover instead strange emblems carved into stone along the route south. Traveling ever closer toward the war between the Visigoths and the English, Edmond and Elspeth suspect they are being drawn into a trap. But with the help of their friends, and faith in themselves, they will face Loki one last time, at an ancient circle of stones that may be their last hope.
