Memories and magic recovered, Frey is restored to the throne. But as she works to regain control of the North, a small silver dagger nearly brings her end. She raises the Seven of her guard and proves her abilities in order to secure her position. But another attempt on her life, from what appears to be fey, reveals not all are pleased with her return. If she could only figure out the force behind the attacks, she might be able to relax enough to decide what to do about her other problem... Chevelle.
