Gwyn is a girl born of blood, snow, and dark promises to the ancient fae. Her fate is bound to the land and powerful creatures long thought dead. In a world where glamors and enchantments are traded like currency, dwarfen kings wage unending war, and only mirrors tell the truth, Gwyn must learn who and what she is to master her unique gifts. For she has earned powerful enemies and the survival of nations might well depend on her. With the help of a mysterious prince, a hunter, and her Shatter-Glass sword, Gwyn must find a way to end the tyranny of the Queen. But there are many dark secrets and ancient monsters in the shadows of Linndorcha. And the greatest secret of all lives within her own blood.
