Raif, wrongly accused and cut off from his clan by the treachery of their new headsman, has a talent for killing that is part of his curse and his burden. But he bears another burden of greater weight. Ash is a sacred warrior to the Sull, an ancient race whose numbers have declined.Raised as a foundling, she never knew her true heritage, she must learn to accept the terrible gifts of her heritage. But as Ash learns more of her greater fate, Raif's task looms dark and desperate, for he must journey through the nightmare realm of the Want, a place where even the Sull now fear to tread. For deep within the Want is the Fortress of Grey Ice, and there he must heal the breach in the Blindwall that already threatens the world. Should he fail, not even Ash's powers can save them.
